Chemical industry classification knowledge

Chemical industry, chemical engineering, chemical technology are referred to as chemical industry. Chemical industry includes petrochemical industry, agricultural chemical industry, chemical medicine, polymer, paint, grease and so on. They appear in different historical periods and have different meanings, but they are closely related, penetrate each other, have continuity, and are endowed with new contents in their development process. Broadly speaking, where the use of chemical methods to change the composition or structure of substances, or the synthesis of new substances, belong to chemical production technology, that is, chemical processes, the resulting products are called chemicals or chemical products.

The rules of the trade

The chemical industry can be divided into fuel chemical industry, inorganic chemical industry, organic chemical industry and fine chemical industry.

First, fuel chemical workers

Fuel chemical industry includes petroleum refining industry, petroleum chemical industry, natural gas chemical industry, coal chemical industry, shale oil industry and so on.

Raw materials: combustible minerals such as oil, natural gas, coal and oil shale

Products: alkanes, alkynes, alkenes, aromatics, alcohols, ketones, phenols, ethers, anhydrides, esters, anhydrides, carboxylic acids, etc.

Second, no machine workers

1. Basic inorganic chemical industry
