1, organic chemicals. It can be divided into alkanes and their derivatives, alkenes and their derivatives, alkynes and their derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylic acids, carbohydrates, heterocycles, nitriles, halogens and amides.

2. Inorganic chemical raw materials. The main raw materials of inorganic chemical products are chemical minerals containing sulfur, sodium, phosphorus, potassium and calcium (see inorganic salt industry) and coal, oil, natural gas, air and water. In addition, by-products and wastes from many industrial sectors are also raw materials for inorganic chemical industry. For example, ammonia contained in coke oven gas during coking production in iron and steel industry can be recovered with sulfuric acid to make ammonium sulfate, and sulfur dioxide in smelting waste gas of chalcopyrite, galena and sphalerite can be used to produce sulfuric acid.
