What kinds of chemical raw materials are there? What are the various uses?
1, organic chemical raw materials
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, the by-products and wastes of many industrial sectors are also raw materials of inorganic chemicals, such as coke oven gas in the coking production process of iron and steel industry, in which ammonia can be recovered with sulfuric acid to make ammonium sulfate, and sulfur dioxide in the smelting waste gas of chalcopyrite, galena and sphalerite can be used to produce sulfuric acid.
Extended data:
Application of inorganic chemical products;
Industrial by-products, such as coke oven gas in the coking process of iron and steel industry, can be recovered from sulfuric acid to make ammonium sulfate, and sulfur dioxide in chalcopyrite, galena and sphalerite smelting waste gas can be used to produce sulfuric acid. Inorganic chemical industry is an early development department in chemical industry, which laid the foundation for the formation and development of unit operation.
The main products are mostly basic chemical raw materials with a wide range of uses. Except for a wide variety of inorganic salts, there are not many other inorganic chemical products. Compared with other chemical products, the output of inorganic chemical products is greater.
Because raw materials and energy costs account for a large proportion in inorganic chemical products, such as synthetic ammonia industry, chlor-alkali industry, yellow phosphorus and calcium carbide production, energy consumption is relatively large. The focus of technological transformation will tend to adopt low-energy technology and comprehensive utilization of raw materials.
The uses of organic chemical products can be summarized into three main aspects:
1, the raw material for the production of polymer chemical products such as synthetic rubber, synthetic fiber and plastic, that is, the monomer for polymerization;
2. Other organic chemical industries, including raw materials for fine chemical products;
3. According to the nature of the product, it is used for some directly consumed substances, such as solvents, refrigerants, antifreeze, heat carriers, gas absorbents, and anesthetics and disinfectants directly used in medicine.
