There are many types of chemical raw materials, and they are widely used. There are as many as 5-7 million kinds of chemicals in the world, more than 100,000 kinds are sold and circulated in the market, and more than 1,000 new chemicals are released every year.Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials.Organic chemical raw materials can be divided into alkanes and their derivatives, alkenes and their derivatives, alkynes and derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, and organic acids , carboxylates, carbohydrates, heterocyclics, nitriles, halogenated, aminoacyl, and other types.Inorganic chemical raw materials are chemical minerals such as sulfur, sodium, phosphorus, potassium, and calcium (see Inorganic Salt Industry), coal, petroleum, natural gas, air, and water.In addition, the by-products and wastes of many industrial sectors are also raw materials for inorganic chemicals, such as coke oven gas in the coking production process in the iron and steel industry. The ammonia contained in it can be recycled with sulfuric acid to produce ammonium sulfate, chalcopyrite, and galena. Sulfur dioxide in the smelting waste gas of ore and sphalerite can be used to produce sulfuric acid.Our company has professional staff engaged in chemical research and development and scientific management, and has multiple sets of high-efficiency and high-sensitivity analytical instruments, specializing in the production and development of pharmaceuticals and their intermediates, cosmetic raw materials and intermediates, food additives, plant extracts, etc. We sincerely hope to establish long-term cooperation and common development with our customers.
