The organic raw materials are petrochemicals made of petroleum and natural gas, and the industries of various organic chemical products are produced or fractionated by the raw material gas after coal gasification and the coal tar recovered by dry distillation. In China's organic chemical industry, the first acetylene route from coal-based calcium carbide, coalification to methanol, formaldehyde route and recovery of coal tar in benzene, naphthalene, anthracene and other routes and the use of grain as raw material fermentation distillation to produce alcohol routes. Organic raw materials are widely used and can be divided into three aspects: one is the raw material used to produce polymer chemical products, that is, the monomer for polymerization; the other is used in other organic chemical industries, including raw materials for fine chemical products; Used in solvents, refrigerants, antifreezes, gas adsorbents, etc. Basic organic chemicals are the basis for the development of various organic chemical products and are a major component of modern industrial structures.
