Chemical materials can be generally divided into two categories of organic and inorganic chemical materials:
1, organic chemical materials
Can be divided into alkanes and their derivatives, olefins and their derivatives, alkynes and derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylic acids, carbohydrates, heterocyclic, nitrile, halogenated, other types of Amino acyls, other types
2, inorganic chemical raw materials
The main raw materials of inorganic chemicals are sulfur-containing, sodium, phosphorus, potassium, calcium and other chemical minerals (see the inorganic salt industry), and coal, petroleum, natural gas, as well as air, water and so on.
In addition, many industrial sectors of by-products and waste, is also the raw material of inorganic chemicals, for example: the iron and steel industry in the coke production process of coke oven gas, which contains ammonia can be recovered from sulfuric acid made of ammonium sulfate, chalcopyrite, galena, sphalerite, smelting of sulfur dioxide can be used for the production of sulfuric acid and other waste gas.

The use of inorganic chemicals:
Industrial by-products such as the iron and steel industry in the coke production process of coke oven gas, which contains ammonia can be used in the recovery of sulfuric acid to be made of ammonium sulfate, chalcopyrite, galena, sphalerite, smelting of sulfur dioxide can be used for the production of sulfuric acid and so on. Inorganic chemical industry in the chemical industry is the development of earlier departments, for the formation and development of unit operation has laid the foundation.
The main products are mostly basic chemical raw materials for a wide range of uses. In addition to a wide variety of inorganic salts, there are not many varieties of other inorganic chemical products. Compared with other chemical products, the output of inorganic chemical products is larger.
As raw materials and energy costs in inorganic chemical products account for a large proportion, such as ammonia industry, chlor-alkali industry, yellow phosphorus, calcium carbide production are more energy-consuming. The focus of technological transformation will tend to use low-energy processes and comprehensive utilization of raw materials.
The use of organic chemical products can be summarized as three main aspects:
1, the production of synthetic rubber, synthetic fibers, plastics and other polymer chemical products, raw materials, that is, the polymerization reaction of the monomers;
2, the other organic chemical industry, including the raw materials of fine chemical products;
3, according to the nature of the product is used for some direct consumption, such as Used as solvents, refrigerants, antifreeze, heat carriers, gas absorbers, as well as anesthetics and disinfectants used directly in medicine.
