The Introduction of Organic Chemicals

Organic chemicals is the abbreviation of organic chemical industry, also known as the organic synthesis industry. It is an industry that mainly produces various organic raw materials with petroleum, natural gas, coal, etc. as basic raw materials. The History of Organic Chemicals The electric furnace method of industrial production of calcium carbide started at the end of the 19th century, which created conditions for the synthesis of basic organic products from acetylene using coal as the basic raw material. Around 1910, the industrial production of tetrachloroethane, trichloroethylene, acetaldehyde, acetic acid, etc. from acetylene was realized in Germany. Then, before World War II, other products synthesized from acetylene were successively put into Germany. Production. Another main route using coal as the basic raw material is to synthesize basic organic products from synthesis gas or carbon monoxide. The success of methanol synthesis in Germany in 1923 started the history of using

What Is Industrial Chemicals?

There are many types of chemical raw materials, and they have a wide range of uses. There are as many as 5-7 million kinds of chemicals in the world, and more than 100,000 kinds are sold and circulated on the market . M ore than 1,000 new chemicals come out every year, and 150-200 kinds of them are considered to be carcinogenic   t hings. Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. Organic chemical raw materials: It can be separated   into alkanes and their derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, and esters , o rganic acids, carboxylates, carbohydrates, heterocycles, nitriles, halogenated, amine acyls, and other types. Inorganic chemical raw materials: The main raw materials of inorganic chemical products are chemical minerals containing sulfur, sodium, phosphorus, potassium, calcium and other chemical minerals (see inorganic salt industry), coal, petr
