Eight important basic organic chemical raw materials,

organic chemical raw materials that many people do not know, now let's take a look!

1. The most basic chemical raw materials of organic chemistry are small molecular substances such as ethylene and propylene, which are mainly obtained by crude oil cracking.

2. Organic chemical industry is the abbreviation of organic chemical industry, also known as organic synthesis industry.

3. It is an industry that mainly produces various organic raw materials based on oil, natural gas, coal, etc.

4. The direct raw materials of basic organic chemicals include hydrogen, carbon monoxide, methane, ethylene, acetylene, propylene, more than four aliphatic hydrocarbons, benzene, toluene, xylene, ethylbenzene, etc.

5. Cracking gas, refinery gas and coal gas from crude oil, petroleum fractions or low-carbon alkanes can be made into aliphatic hydrocarbon raw materials for different purposes after separation treatment; Aromatic raw materials can be separated from reformed gasoline catalytically reformed, pyrolyzed gasoline by hydrocarbon cracking and coal tar distilled by coal; Appropriate petroleum fractions can also be used directly as feedstock for certain products; Wet natural gas can separate other low-carbon alkanes other than methane; Synthesis gas can be made from coal gasification and vapor conversion or partial oxidation of natural gas, refinery gas, petroleum fractions or crude oil; Calcium carbide obtained from coke, or acetylene can be obtained by cracking natural gas and naphtha.

6. In addition, raw materials can also be obtained from agricultural and forestry by-products.

7. The use of basic organic chemical products can be summarized into three main aspects: (1) raw materials for the production of synthetic rubber, synthetic fibers, plastics and other polymer chemical products, that is, monomers of polymerization reaction; (2) Other organic chemical industries, including raw materials for fine chemical products; (3) According to the nature of the product, it is used for certain direct consumption, such as solvents, refrigerants, antifreeze, heat carriers, gas absorbers, and anesthetics, disinfectants directly used in medicine.

8. Ethylene, propylene, butene and other small molecule olefins.

9. It is mainly extracted from crude oil cracking products. This article is now shared, I hope it will be helpful to everyone.
