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
Preparation Method:
Add 100g (1.53mol) of zinc amalgam, 250ml of concentrated hydrochloric acid and 50ml of water into the reaction bottle equipped with stirrer, reflux condenser and vent pipe (extending into the bottom of the bottle), add 40g (0.35mol) of octanone-2 (2) under stirring, and slowly inject hydrogen chloride gas. If the reaction is too violent, the hydrogen chloride gas can be suspended. After 2-3H, most of the zinc amalgam reaction was completed, hydrogen chloride was stopped and placed overnight. Remove the agitator and change to steam distillation unit for steam distillation until the distillate is transparent. The upper oil layer was separated, washed twice with distilled water, fractionated after drying with anhydrous sodium sulfate, and the fraction at 124-126 ℃ was collected to obtain 26G octane (1) with a yield of 58%.
