◎ Chemical Hotspots
The market weighed the tight supply situation, the weaker than expected U.S. employment data and the outlook of the Federal Reserve’s monetary policy, and the international oil price closed down after rising sharply in the session. NYMEX crude oil futures 02 contract fell by US $0.56/barrel or 0.70% at 78.90; Ice oil distribution futures 03 contract 81.75, down $0.24/barrel or 0.29%.
◎ How does the sudden tension in Kazakhstan affect the crude oil market?
Due to the strong resistance of crude oil pipeline transportation to epidemic situation, bad weather and other factors, unless the pipeline is damaged or the input end of the oil field is damaged, the transportation capacity will remain stable. Therefore, the impact of the situation in Kazakhstan on China’s import of crude oil from Kazakhstan may be slight. Previous tensions in Myanmar similar to this incident failed to have a significant impact on the transportation of China Myanmar crude oil pipeline. The tension in Kazakhstan this time, unless the deterioration of the situation affects the facilities related to crude oil production and export, the impact on the international crude oil price may be very limited, and it will not restrict China’s normal crude oil import. Junyuan Petroleum Group will continue to pay attention to the follow-up progress of this event.
The prices of n-Pentane and Isopentane foam blowing agents rose by 0.76% and 1.56% respectively today.
Market review from January to June 2021:
From January to June 2021, the domestic pentane foaming agent market showed an “m” trend, and the overall price was higher than that of the same period in previous years. The highest node is one week after May Day, and the price is 5800 yuan / ton. The lowest node is at the beginning of the year, and the price is 4500 yuan / ton, and the difference between high and low prices is 1300 yuan / ton.
The first stage: from January to mid March (price rise stage): the price of pentane foaming agent rises with the support of good cost and demand. On the cost side, the oil market is improving, and the price of raw material mixed C5 rises, which gives a certain rise support to the cost side; On the demand side, the downstream EPS is boosted by the rise of styrene. In addition, the terminal purchase is active, the EPS price rises, and the price receiving capacity of auxiliary materials is strengthened, giving pentane foaming agent some room for rise.
The second stage: from mid March to early April (price downward stage): the price of pentane foaming agent decreased rapidly due to the weakening cost side and the slowdown of downstream demand. On the cost side, crude oil rose in mid March and fell sharply, bulk commodities generally fell sharply, the raw material market fell, and the cost support was insufficient; On the demand side, the price of styrene has weakened significantly, the EPS market has fallen sharply, coupled

with the slow improvement of downstream packaging and insulation demand, the slow delivery speed of merchants, the obvious pressure on the finished product inventory of most EPS factories, the reduction and shutdown of some EPS factories in East and South China, and the overall transaction atmosphere of the market is insufficient.
The third stage: from early April to mid May (price upward stage): pentane foaming agent is supported by cost rebound, coupled with tight supply of some positive high models in the field, and the price is upward. On the cost side, boosted by the rebound in the oil market, the price of raw material mixed C5 rose; On the supply side, due to the slow price increase and pressure on the cost, pentane foaming agent continued to reduce the supply in some factory parking lots, and many companies mainly sold inventory; On the demand side, most downstream EPS demand models are positive high. In addition, the polyurethane industry has a strong demand for n-pentane monomer, the positive high models in the field are tight, and the price rises accordingly.
The third stage: from mid May to the end of June (price downward stage): the price of pentane foaming agent is downward due to the weakening cost, insufficient downstream demand and increased on-site supply. In terms of cost, due to the strict investigation of environmental protection, safety and taxation, the social oil activities are reduced. In addition, the use of mixed C5 decreases as the weather turns hot, the demand of raw material mixed C5 is restricted, the price is at the bottom, and there is no strong support for the cost of pentane foaming agent; On the supply side, the on-site supply increased, and Jiangsu Xinhai, Dongying Runze and zhongtuolihe added pentane supply, increasing the competitive pressure; On the demand side, the price of styrene fell sharply, the EPS market fell, the terminal merchants mainly replenished at different stages, and the overall delivery was cold. In addition, affected by the inspection, some factories were shut down for transformation or decline, the overall operation of EPS was insufficient, and the demand for pentane foaming agent decreased.
According to the statistics of internal chemical data of Junyuan Petroleum Group, the total output of pentane foaming agent in China from January to June 2021 was 139,500 tons, of which the output from April to June was 97,000 tons, a decrease of 11,100 tons compared with 108,100 tons in 2020.
The average profit of the domestic pentane foaming agent industry has declined continuously for nearly three years. The average profit from January to June 2021 was 186.45 yuan / ton, down 131.41 yuan / ton from 317.86 yuan / ton in 2020, and the average profit in 2019 was 550.45 yuan / ton, down 364 yuan / ton. At present, it is at the lowest profit level in recent three years.
Analysis on price fluctuation of pentane products in 2021
Hydrocarbon prices have been stable in the last three days. Today is the last day of China's New Year's Day holiday. Each chemical enterprise has not started yet, and the order delivery of each solvent factory is carried out as usual. The staff of the sales department, freight forwarding enterprise, logistics enterprise and the production and loading and unloading team of the factory are usually on duty on a 7 / 24 rotation all year round.
Analysis on price fluctuation of pentane products in 2021
In 2021, the price of domestic pentane products rose across the board compared with last year. The price trend of the whole year is obvious from the figure, which is higher than that of the previous two years. Especially at the end of October, the price soared to a historic high, and the annual low was at the beginning of the year. Throughout the year, the supply and demand factors of n-Pentane, Isopentane, Foaming Agent and Cyclopentane changed a lot. In February and March, the extremely cold weather in Europe and America disturbed the supply pattern and flow direction, and the production units at home and abroad were unstable. In the second half of the year, the domestic units stopped periodically, the supply decreased, and the market price gradually showed an upward trend. With the off-season of downstream demand, the export cost increased, the market focus returned, and the phased decline at the end of the year ended.
Throughout the year, in addition to the fundamentals of supply and demand, the market is still affected by many factors: the domestic epidemic situation is effectively controlled, but the foreign epidemic situation is continuous, which has a certain inhibition on exports and shipping, and the crude oil market is volatile. In the second half of the year, the global market boom is gradually depressed, and it is difficult for the solvent industry terminal to improve. The demand side is gradually unable to bear high-priced raw materials, so it is "GivingUp" waiting at the end of the year, Hydrocarbon production plants are passive under pressure.
In the twinkling of an eye, the Spring Festival in 2022 is coming. China's Spring Festival is as important as Christmas in the West. It is believed that many people are looking forward to returning home to reunite with their relatives, the annual Spring Festival transportation is about to start, and college students are about to have a winter vacation. The Spring Festival is a festival that every Chinese people look forward to.

What are Hydrocarbons?
Core tip: Hydrocarbon products are widely used in daily production and life. Hydrocarbons are divided into alkanes, cycloalkanes and aromatic hydrocarbons. HCR433B hydrocarbon refrigerant is the most representative in commercial life, while HCR436A hydrocarbon refrigerant is the most representative in automobile.
“Hydrocarbon” is a common name for hydrocarbons. Organic compounds composed only of carbon and hydrogen are called hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine vapor and oxygen to produce hydrocarbon derivatives. Saturated hydrocarbons (and benzene) do not react with strong acids, bases and strong oxidants (such as potassium permanganate), but unsaturated hydrocarbons (olefins, alkynes and benzene homologues) can be oxidized or react with hydrogen halide. There are many kinds of hydrocarbons, and there are more than 2000 kinds of hydrocarbons with known structures. Hydrocarbon is the parent of organic compounds. Other kinds of organic compounds can be regarded as derivatives generated by the substitution of one or more hydrogen atoms in hydrocarbon molecules by atoms or atomic groups of other elements.
Hydrocarbons in petroleum
Hydrocarbon in Chinese is the abbreviation of hydrocarbon, which is composed of “fire” in “carbon” and “巠” in “hydrogen”. Hydrocarbons are divided into saturated hydrocarbons and unsaturated hydrocarbons. Most hydrocarbons in petroleum are saturated hydrocarbons, while unsaturated hydrocarbons such as ethylene and acetylene can be obtained only in the process of petroleum processing. There are three types of hydrocarbons in petroleum:
(1) Alkane
It is a chain hydrocarbon with single bond between carbon atoms. Due to the different number of carbon and hydrogen atoms that make up hydrocarbons, petroleum contains hydrocarbon molecules with great and small differences. Alkanes are named according to the carbon atoms and number contained in the molecule. Those with less than 10 carbon atoms are represented by a, B, C, D, e, hexane, heptane, octane, nonane and decane from 1 to 10. Those with more than 11 carbon atoms are represented by numbers. Alkanes in petroleum include normal alkanes and isoalkanes. The content of n-alkanes in paraffin based petroleum is high; The content of isoalkanes in pitch based petroleum is high. Alkanes are also called alkane hydrocarbons. The general formula of the molecular formula of alkanes is CnH2n + 2, where n represents the number of carbon atoms in the molecule. 2n + 2 represents the number of hydrogen atoms. Under normal temperature and pressure, C1-C4 alkanes are gaseous and exist in natural gas; C5-c16 alkanes are liquid and the main component of petroleum; Alkanes above C16 are solid.
(2) Cycloalkanes
As the name suggests, it is a ring structure. The most common is a ring composed of five or six carbon atoms. The former is called cyclopentane and the latter is called cyclohexane. The general formula of the molecular formula of cycloalkanes is CnH2n. Cycloalkanes are also called cycloalkanes.
(3) Aromatic hydrocarbon
Also known as aromatic hydrocarbons. It is generally composed of one or more six membered rings with special structure. The simplest aromatic hydrocarbons are benzene, toluene and xylene. They can be obtained from the production of platinum reforming unit in the oil refining process. The general formula of the molecular formula of aromatic hydrocarbons is CNH2N-6.
To sum up, hydrocarbons exist in many things, such as fuels and cleaning agents, and are widely used in daily life.
The organic solvent purification system can process solvents:
Aromatic and aliphatic hydrocarbons: Pentane, n-Hexane, Cyclohexane, n-Heptane, Toluene, Benzene
Ethers: ether, tetrahydrofuran, dimethyl ether
Chlorinated solvent: dichloromethane, chloroform, chlorobenzene
Amine solvents: triethylamine, pyridine, diisopropyl ethyl amine
Alcohol: methanol, ethanol
Other general solvents: acetonitrile, dimethylformamide, dimethyl sulfoxide, acetone
Today, the price of n-Heptane plunged by 6.58 percentage points. The price of pentane blowing agent increased by 0.85% on December 24, and then decreased by 0.84% on December 28. The continuous rise and fall of prices has always been the characteristic of foaming agent products, and the market price fluctuates too much due to the cost of raw materials.
The recent favorable factors in the crude oil market have the upper hand, and the crude oil price may maintain a strong trend and continue to operate at a relatively high level.
