Gas Chromatogram of n-Pentane

Chromatogram refers to the image of the detection signal of the separated component over time. The shape of chromatogram varies with different chromatographic methods and detection records. The chromatograms of head-on chromatography and displacement chromatography are a series of steps; In elution chromatography, if a differential detector is used, the graph of the detection signal of the separated components changing with time is a group of chromatographic peaks similar to Gaussian distribution, the ordinate of the chromatogram is the response signal of the detector, and the abscissa is time, volume or distance.

Name in Chinese: Gas Chromatography 气相色谱图
Definition: time distribution image of separated component detection signal
Pinyin: Q ì Xi à ng s è p ǔ  tú
Name in English: chromatogram

Related Terms
⊕ chromatogram – the signal time curve obtained when the sample flows through the chromatographic column and detector, also known as the chromatographic outflow profile.
⊕ baseline — after the mobile phase is flushed and the column and mobile phase reach equilibrium, the detector measures the outflow curve for a period of time. Generally, it should be parallel to the time axis.
⊕ noise – fluctuation of baseline signal. It is usually caused by poor power contact or instantaneous overload, unstable detector, bubble in mobile phase or contamination of chromatographic column.
⊕ drift – the slow change of the baseline over time. It is mainly caused by the instability of operating conditions such as voltage, temperature, mobile phase and flow. The pollutants or stationary phase in the column will also drift after being eluted continuously.
⊕ chromatographic peak – the curve generated by the corresponding continuous signal when the group is shunted through the detector. A projection on an outflow curve. The normal chromatographic peak is similar to the symmetrical normal distribution curve (Gaussian Gauss curve). There are two kinds of asymmetric chromatographic peaks: leading peak and tailing peak. The former is rare.
⊕ tailing factor (T) — t = B / A, which is used to measure the symmetry of chromatographic peaks. Also known as symmetry factor or asymmetry factor, t should be 0.95 ~ 1.05 according to Chinese Pharmacopoeia. T1. 05 is the tailing peak.
⊕ peak bottom – the distance from the starting point of the peak on the baseline to the end point.
⊕ peak height (H) – the distance from the highest point of the peak to the bottom of the peak.
⊕ peak width (W) – the distance between the two tangents at the inflection points on both sides of the peak and the two intersections of the baseline. W=4 σ。
⊕ peak width that height (WH / 2) – peak width at half of peak height. Wh/2=2.355 σ。
⊕ standard deviation, σ)—— Half of the peak width of the normal distribution curve when x = ± 1 (inflection point). The inflection point of normal peak width is 0.607 times of peak height. The standard deviation indicates the dispersion degree of components in the process of flowing out of the chromatographic column. σ Small, small dispersion, high pole concentration, thin peak shape and high column efficiency; conversely, σ Large, fat peak shape and low column efficiency.
⊕ peak area (a) – the area surrounded by the peak and the peak bottom. A= ×σ× h=2.507 σ h=1.064Wh/2h。

11th GPCA Plastics Conference

25/05/2022-26/05/2022, Riyadh, Saudi Arabia
The COVID-19 pandemic has reemphasized the indispensable role of plastics in our everyday life. Amongst others, medical-grade masks, gloves, PPE, various medical equipment along with several packaging applications have proved to be a lifesaver and played a vital role in protecting the health and safety of frontline workers as well as civilians during the pandemic. However, the manner in which their disposal is handled poses a serious environmental challenge. This is creating an urgent need to change our mindset from the existing linear take-make-dispose model and shift towards a closed-loop, reusability, and recycling-focused model. This requires a systemic transformation where all waste is viewed as a valuable resource and its value is captured within the economy. This can be achieved on the back of innovation through collaboration along the value chain, which was brought to the limelight during the pandemic.

On the flip side, an increased focus on recycling is both a growing threat and an opportunity to the virgin polymers industry. This is making plastic producers, refiners, waste management companies innovate new business models to develop a global economy where plastics are never wasted. Although collection and sorting remain the most challenging barriers to achieve a circular economy, advancements in advanced recycling technologies are aiming to ease the process.

Raffinate oil

In chemical separation terminology, the raffinate (from French raffiner, to refine) is a product which has had a component or components removed. The product having the removed materials is referred to as the extract. For example, in solvent extraction, the raffinate is the liquid stream which remains after solutes from the original liquid are removed through contact with an immiscible liquid. In metallurgy, raffinating refers to a process in which impurities are removed from liquid material.

Fenpropathrin

Fenpropathrin

Pyrethroid Insecticide
Fenpropathrin
Fenpropathrin, or fenopropathrin, is a widely used pyrethroid insecticide in agriculture and household. Fenpropathrin is an ingestion and contact synthetic pyrethroid. Its mode of action is similar to other natural and synthetic pyrethroids where in they interfere with the kinetics of voltage gated sodium channels causing paralysis and death of the pest. Fenpropathrin was the first of the light-stable synthetic pyrethroids to be synthesized in 1971, but it was not commercialized until 1980. Like other pyrethroids with an α-cyano group, fenpropathrin also belongs to the termed type II pyrethroids. Type II pyrethroids are a more potent toxicant than type I in depolarizing insect nerves. Application rates of fenpropathrin in agriculture according to US environmental protection agency varies by crop but is not to exceed 0.4 lb ai/acre.

Diuretic

Class of Drugs
A diuretic is any substance that promotes diuresis, the increased production of urine. This includes forced diuresis. A diuretic tablet is sometimes colloquially called a water tablet. There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys. There exist several classes of diuretic, and each works in a distinct way. Alternatively, an antidiuretic, such as vasopressin, is an agent or drug which reduces the excretion of water in urine.

What is the difference between upstream and downstream processes?

Whereas, the downstream process involves the processing of those cell masses from the upstream to meet quality and purity requirements as per need. This process involves cell disruption, purification and final polishing of the products. The first process involved as stated above in Upstream involves the separation of cells.

What are the different types of downstream businesses?

Companies engaged in the downstream process include oil refineries, petrochemical plants, petroleum product distributors, natural gas distributors, and even retail outlets. Some obvious oil and natural gas products are fuels like diesel, gasoline, kerosene, and jet fuels.

What connects the upstream sector to the downstream sector?

Midstream sector The midstream sector connects the upstream sector to the downstream sector. Often times it is lumped in with the downstream sector. Pipelines and other transport systems can be used to move crude oil from production sites to refineries and deliver the various refined products to downstream distributors.

What are downstream activities?

Downstream activities revolve around turning crude oil and natural gas into the finished products that consumers use. The closer the company is to supplying customers with products, the further downstream they are in the supply chain.

Downstream vs Upstream The main difference between upstream and downstream production processes is that the upstream process refers to all the activities performed to gather all the initial materials for manufacturing, whereas the downstream process includes the refining of crude oil and the retailing of the products to the consumers.

What does upstream mean in the oil and gas industry?

Upstream is a term for the operations stages in the oil and gas industry that involve exploration and production. Oil and gas companies can generally be divided into three segments: upstream, midstream, and downstream. Upstream firms deal primarily with the exploration and initial production stages of the oil and gas industry.

How to purify n-Heptane?

How to purify n-Heptane?
There are two methods to purify n-Heptane:

Taking n-heptane as the model compound of alkanes in light straight run naphtha, the cracking reaction of n-heptane on HZSM-5 catalyst was studied and compared with the cracking reaction of 1-heptene. The effects of hydrothermal treatment and carrier properties on the cracking reaction were investigated The results show that the content of small molecular alkanes such as hydrogen, methane and ethane in n-heptane cracking products is much higher than that in 1-heptane cracking. It is speculated that it is mainly caused by the unique single molecular cracking path of alkanes, and the content of low-carbon olefins such as propylene and butene in liquefied gas (LPG) is low; After hydrothermal treatment, the amount of acid decreased sharply, and the relative content of strong B acid decreased, resulting in significant reduction of catalyst activity, reduction of hydrogen transfer reaction and significant increase of olefin degree in cracking gas At the same time, the molar ratio of C3 / C4 in the product decreased, which reduced the probability of inferring the single molecular path in the cracking reaction The carrier also has a great influence on the cracking reaction behavior of n-heptane. The presence of Lewis acid in the carrier can promote the conversion of n-heptane and increase the proportion of BIMOLECULAR CRACKING path in the initial reaction Generally speaking, compared with olefin molecules, alkanes have lower reaction activity and olefin selectivity, so they are not an ideal raw material for catalytic cracking on molecular sieve catalysts to produce low-carbon olefinsRemoving impurities from the heptane stream by contacting the heptane stream with an acidic catalyst, wherein the contact reduces the concentration of one or more near boiling impurities, one or more olefins, or both. Impurities are isomerized into substances with low octane number or boiling point not close to the boiling point of n-heptane through contact with acidic catalyst, which helps to separate impurities by distillation. Near boiling point impurities may include compounds such as cis-1,2-dimethylcyclopentane and methylcyclohexane, or compounds with boiling points in the range of about 96.5 to about 100.5 degrees Celsius at a standard pressure of 760 Torr, including compounds such as cis-1,2-dimethylcyclopentane and methylcyclohexane. The concentrations of cis-1,2-dimethylcyclopentane and methylcyclohexane can be reduced by at least 25% and 10% by weight, respectively. The olefin concentration measured by bromine index can be reduced by at least about 25% (by weight).

1. After nickel catalyzed hydrogenation, a small amount of normal olefins are saturated and converted into normal alkanes, and the iodine value is reduced to less than 0.1g iodine / 100g. Finally, standard n-Heptane with purity of 99.9% was obtained by distillation. Industrial grade n-Heptane can also be purified by concentrated sulfuric acid washing and methanol azeotropic distillation.
2. Hydrocarbon fraction of petroleum. It can contain n-Heptane, dimethylcyclopentane, 3-ethylpentane, methylcyclohexane and 3-methylcyclohexane.

Purification Methods of n-Heptane

Light naphtha isomerization oil does not contain sulfur, aromatics, olefins and other substances. It is one of the blending components of clean gasoline with high octane number. Normal C5 and C6 isomerization in light naphtha is easy and has realized industrial production, while long-chain alkane isomerization represented by n-heptane is difficult. Once a breakthrough is made, it will bring great technological progress to the production of high octane number gasoline. Ptwo3 / ZrO2 Catalyst has the advantages of good thermal stability, strong acidity, simple preparation method, reusable and good isomerization performance. It has become a research hotspot of n-heptane isomerization catalyst. In this paper, Pt / WO3 / ZrO2 Catalyst was further modified by Cr and other metals to improve the performance of the catalyst in n-heptane isomerization. The main conclusions are as follows: (1) Pt / WO3 / ZrO2 Catalyst Modified by rare earth metals such as PR, CE, La and Rb and transition metals such as Cr, Co, Zn and Fe was prepared by impregnation method. The modified catalyst was characterized by XRD, NH3-TPD, bet, H2-TPR and SEM, Combined with the fixed bed reactor, the catalytic performance of the catalyst for n-heptane isomerization was analyzed and evaluated. The results show that among the above metal modified catalysts, Cr2O3 Pt / WO3 / ZrO2 Catalyst has large specific surface area and strong acidity, and shows better catalytic activity in n-heptane isomerization. (2) The effects of WO3 content, Cr content, calcination temperature and calcination time on the isomerization of n-heptane over Cr2O3 Pt / WO3 / ZrO2 Catalyst were investigated. The results showed that the isomerization performance of the catalyst was better when the load of WO3 was 18wt%, the content of Cr was 1.0wt%, the calcination temperature was 800 ℃ and the calcination time was 3H. At this time, the yield of isoheptane was about 73% and the conversion of n-heptane was about 82%. (3) The effects of reaction pressure, reaction temperature, molar ratio of hydrogen to hydrocarbon and space velocity reaction conditions on n-heptane isomerization over Cr2O3 Pt / WO3 / ZrO2 Catalyst were investigated. The results show that the catalytic performance is the best when the reaction pressure is 1.0MPa, the reaction temperature is 220 ℃, the molar ratio of hydrogen to hydrocarbon is 9 and the space velocity is 1.05 ~ 1.4h-1. The yield of n-heptane is about 75%. (4) The stability of Cr2O3 Pt / WO3 / ZrO2 Catalyst was investigated, and Cr2O3 Pt / WO3 / ZrO2 Catalyst was applied to the isomerization of light naphtha raw materials. The results showed that Cr2O3 Pt / WO3 / ZrO2 Catalyst did not inactivate after 500 hours of n-heptane isomerization, and the catalyst was stable; Cr2O3 Pt / WO3 / ZrO2 Catalyst has good isomerization performance in actual naphtha raw materials, and the octane number of chromatography is increased by about 28 units.

n-Heptane, CAS 142-82-5

 
North America
 
In North America, the price trend of n-heptane marked stability during October and November. Pricing dynamics of upstream crude oil during these months was showcasing uptrend in October and marginally eased in November. While showcased significant ease in December, providing ease to downstream heptane in the domestic market. Meanwhile, downstream paints and coatings sector remained comparatively dull than other segment throughout the quarter, which also remained a major factor behind overall lower offtakes for the product across regional market. Thus, overall market of n-heptane was observed low in the ending December of quarter 4 of 2021.
 
Asia
 
In Asia, during the fourth quarter of 2021, n-heptane prices rose consistently, which was assessed around USD 2025/MT in India during October. Rising crude oil value remained a prime factor that pushed up the prices of n-heptane during Quarter 4 across regional market. However, the market of crude oil in China was observed fluctuating in the meantime and increased by the end of December, which resulted into overall stability in the price of n-heptane. Furthermore, demand for the product from the downstream solvent market remained firm, while traders noted ample offtakes from niche buyers.
 
Europe
 
The overall outlook showed that the price of n-heptane witnessed firmness during the Q4 2021 across European market. However, due to high natural gas prices amidst rising upstream crude oil values, input cost rose exponentially for several commodities including n-heptane. As the consumption increased in October and November so the prices increased for the product, while improved upstream crude oil availability in Europe market provided some ease to prices in December and the market of paints and coatings was stable throughout the quarter.
 
 
For the Quarter Ending September 2021

North America
 
In the North America region, n-Heptane prices traced an upward trajectory during the third quarter of 2021 supported by the sturdy demand from the downstream rubber and pharmaceutical industry. The arrival of hurricane Ida in the Gulf Coast of US hindered crude oil production, which resulted in the feeble supply of derivatives. The situation consequently pushed up the values of n-Heptane in the region. During the last month of the quarter, crude production improved, and the demand supply gap paved normalcy which finally dragged the prices of n-Heptane in both domestic and international market. 
 
Asia Pacific 
 
In Asia, n-Heptane market registered mixed sentiments during the third quarter of 2021 depending upon the demand pattern as well as the supplies of the product in the region. In India, under frequently changing market scenario, significant fluctuations in the n-Heptane values were observed. Demand for n-Heptane remained strong in the Indian market, while disturbed trade activities due to logistical issues and constrained availability of shipping containers kept on influencing the overall price trend of the product. In addition, volatility in upstream crude also supported the pricing trend of n-Heptane during this quarter. Prices of n-Heptane rose from USD 1738.47/MT to USD 1811.92/MT during July to August in India. However, a slight dip in the prices of n-Heptane was seen in September.    
 
Europe
 
In Europe, n-Heptane prices observed an upward trend during the third quarter of 2021 followed by the lower production rates due to the energy crisis as well as the delayed imports. However, the demand from the downstream sectors including Pharmaceuticals and Rubber continued to be buoyant throughout the quarter. Further exorbitant freight charges and limited availability of shipping containers further sent ripples to the n-Heptane prices in the region. 
 
For the Quarter Ending June 2021
 
North America
 
The resumption in industrial activities in the US Gulf Coast improved the supply outlook during the second quarter of 2021. However, some hinderance was observed as the colonial pipeline was shut for a week due to the cyber-attack in the second quarter. Amidst the recovered supply chains and continuous industrial activities, the demand supply gap narrowed which provided a further ease in prices in the regional domestic markets. Demand remained firm as orders were piled up, along with the continuous demand from the rubber and pharmaceutical industries.
 
Asia Pacific
 
During the second quarter of 2021, market activities remained subdued in the Asia Pacific region due to unprecedented rise in Covid cases. The second Covid wave in India restricted the public movement thus lowering the offtakes from bulk buyers. As a repercussion of reduced market activities in India and the surged inventories level, prices of n-Heptane stabilized in the Indian market with discussions drifting to USD 1824 per tonne in June. In China, import of the brent crude oil surged, which proportionally improved the availability of n-Heptane in the Chinese domestic market. In China, offtakes remained consistent from the rubber industries and pharmaceutical sector.
 
Europe
 
The n-Heptane market in the European region showcased mixed sentiments during the second quarter. In the first half, supply remained constraint owing to the low production levels at several manufacturing facilities. Whereas condition improved in the second half, as the supply chain restored with better distribution practices of crude oil. Demand remained persistent from downstream rubber and pharmaceutical sector. As a ripple effect, prices in the European region remained stable to firm in the second quarter of 2021.
 
For the Quarter Ending March 2021
 
North America
 
The North American region experienced the severe downfall in the crude oil inventories as the extreme freeze weather conditions in Texas and nearby of US Gulf coast area resulted in curtailed petrochemical production as several Naphtha crackers opted for force majeures in the region. Exxon Mobil shut its 369,024 bpd Beaumont refinery and 560,500 bpd Baytown refinery and several chemical plants in Texas along with its Louisiana, plants also facing operational issues. Reduced upstream run rates coupled with market tightness prompted ExxonMobil to increase the prices of n-Heptane by USD110/MT in March.
 
Asia-Pacific (APAC)
 
n-Heptane supplies were tight in the APAC region during Q1 2021, amidst major converters responding to the Saudi Aramco’s output cut in Crude Oil extraction by 1 Million barrels/day which proportionally surged the prices of crude barrels across in the Asian markets. Demand in the region surged as the buyers started to stockpile their inventories ahead of Chinese lunar new year holidays and uncertainty over import supplies. Due to sharp rise in upstream rates and shortage in market supplies, price of n-Heptane in the Indian market surged USD 1775/MT for April deliveries.  
 
Europe
 
The supplies of n-Heptane in the region were constrained, owing to reduced imports from overseas throughout the quarter due to surging freights, higher shipment cost and Suez Canal blockage. Naphtha crackers in the region were heard operating at reduced capacity due to severe freeze weather conditions in the northwest Europe. Demand however surged due to consistent offtakes from the downstream solvent sector throughout the quarter.             

For the Quarter Ending December 2020
 
Asia
 
Buoyed by increasing demand and maintenance turnarounds reported by some Chinese producers, n-Heptane offers were raised by a significant percentage in Q4. The price of n-Heptane was susceptible to huge fluctuations in the quarter due to volatile upstream dynamics. Resilient demand during the fourth quarter from the pharmaceutical industries raised the market sentiments. Price surge was driven by increasing cost pressure on the raw material front because of restricted and delayed overseas shipments. An uptrend was observed on the global level due to rising efforts for sustained economic and financial revival.
 
Europe
 
Alleviating demand for n-Heptane from the pharmaceutical intermediates and industrial solvents endorsed the product’s market outlook in Europe. Firming crude oil, however created a hazy picture in the European Union which was heard planning to increasing its crude oil imports to support the economy. In early November, the accessibility of Europe for n-Heptane improved as feedstock constraints in the upstream market had mostly been leveraged because of sustainable recovery policies along with supply chain. Several European countries were heard emerging from the crisis at varying rates as plant utilization rates gradually enhanced due to significant pick-up in demand.
 
North America

Supply of n-Heptane eased after mid-October as producers increased production rates after plant outages caused by seasonal hurricanes. With most manufacturers eyeing on recovery in demand post the roll out of vaccine towards the year-end, operating rates were pushed higher by December. Recovery in upstream crude oil prices, however capped the producer’s margins. The growing demand for high purity material from the pharma industry, combined with an uptrend in paints and coatings manufacturing boosted the market sentiments.

About

n-Heptane is a straight chain alkane having a chemical formula of C7H16. It is principally derived from crude oil and is highly volatile in nature. n-Heptane is a clear, colourless liquid with an odour similar to petroleum. It cannot be dissolved in water because it reacts violently with water. It is miscible with ethyl alcohol, acetone, benzene, chloroform, and petroleum ether; soluble in carbon tetrachloride; very soluble in ethanol. n-Heptane can be manufactured from petroleum fractional distillation accompanied by rectification. It is also obtained as a by-product from naphtha cracking. It is used in various industries such as adhesives, paints & coatings, ink printing, pharmaceuticals etc. Due to its hydrocarbon chemical composition, which liberate large quantities of heat energy during hydrocarbon combustion, heptane is a perfect fuel source for pressurised, outdoor liquid fuel. Apart from its use in engine fuels, n- Heptane is mainly used as an extraction solvent in the processing of vegetable oils. In addition, higher utilization of n-Heptane for different applications has fueled the growth of the plastic & polymer industry, which in turn is rising the worldwide consumer demand for n-Heptane.

n-Pentane Catalytic

n-pentane catalytic cracking was studied over a series of MFI zeolites with varying SiO2/Al2O3 ratios (30, 80, 280, 500, and 1500) using a fixed-bed reactor operated at temperature 550 to 650 °C. Other MFI zeolites (SiO2/Al2O3 = 280) with various crystal morphology and size (such as large crystal and nano size) were also synthesized and tested for n-pentane cracking. The effects of MFI zeolite modification with ammonia and phosphorus on its physiochemical properties and catalytic activity were investigated. Among the parent MFI zeolites, MFI (280) demonstrated high selectivity (51%) towards light olefins (C3=/C2= = 0.7) at 650 °C with undesired C1-C4 alkanes (38%). Surface modified MFI (280) zeolites of different crystal size and morphology showed improvement towards propylene selectivity by suppressing undesired reactions.

3=/C2= = ∼1.3 and reduce undesired C1-C4 alkanes (8%) formation due to suppressed strong acidic sites. The characterization and evaluation results for the modified MFI (280) revealed that the incorporation of phosphorous created moderate acidic sites, which were stabilized by some non-framework aluminum species, thereby leading to suppressing the formation of undesired C1-C4 alkanes with improved light olefins selectivity.
