Raw material classification
The direct raw materials for basic organic chemical industry include hydrogen, carbon monoxide, methane, ethylene, acetylene, propylene, C4 and above fatty hydrocarbons, benzene, toluene, xylene and ethylbenzene (which come from petroleum, natural gas, and coal). By separating and processing cracked gas from crude oil, petroleum fractions or low-carbon alkanes, refinery gas, and coal gas, fatty hydrocarbon raw materials for different purposes can be produced; Aromatic raw materials can be separated from reformed gasoline from catalytic reforming, cracked gasoline from hydrocarbon cracking, and coal tar from coal dry distillation; Appropriate petroleum fractions can also be directly used as raw materials for certain products; Wet natural gas can separate low-carbon alkanes other than methane; Synthetic gas can be produced by steam conversion or partial oxidation of coal gasification and natural gas, refinery gas, petroleum fractions, or crude oil; Calcium carbide produced from coke, or acetylene can be produced from natural gas or naphtha cracking. In addition, raw materials can also be obtained from agricultural and forestry by-products.
Product classification
Basic organic chemical products can also be classified according to the raw materials used:
① Synthetic gas products (see Syngas).
② Methane based products (see methane).
③ Ethylene products (see ethylene).
④ Propylene products (see propylene).
⑤ C4 and above fatty hydrocarbon products (see C4 fraction; C5 fraction).
⑥ Acetylene series products (see acetylene).
⑦ Aromatic hydrocarbon products (see aromatics). Starting from each type of raw material mentioned above, a series of products can be produced.
Product Usage
The use of basic organic chemical products can be summarized into three main aspects: ① raw materials for producing synthetic rubber, synthetic fibers, plastics, and other polymer chemical products, namely monomers for polymerization reactions; ② Other organic chemical industries, including raw materials for fine chemical products; ③ Used for certain direct consumption according to the nature of the product, such as as as solvents, refrigerants, antifreeze agents, heat carriers, gas absorbers, as well as anesthetics and disinfectants directly used in medicine. From the above, it can be seen that the importance of basic organic chemical industry is the foundation for the development of various organic chemical production, and it is a major component of modern industrial structure.
