What are the chemical raw materials?

There were many chemical material varieties, mainly is the material in chemical industry, used to produce chemical products, chemical material can be divided into two types: organic chemical material and inorganic chemical material, chemical material in the world is about 500 ~ 7 million, the flow of sale in the market now is beyond 100000, every year there are more than 1000 kinds of new chemicals, Of these, 150 to 200 are considered carcinogens.

According to the material

(1) Organic chemical materials can be divided into alkanes and their derivatives, olefin and its derivatives, alkynes and derivatives, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylic acids, carbohydrates, heterocycles, nitriles, halogens, amines and so on.

(2) The main materials of inorganic chemical materials are sulfur, sodium, phosphorus, potassium, calcium and other chemical minerals (see inorganic salt industry) and coal, oil, natural gas, air, water, etc. In addition, the by-products and wastes of many industrial sectors are also the material of inorganic chemicals.

According to the different production process

1.Starting material: air, water, fossil fuels (coal, oil, natural gas, etc.), sea salt, various mineral resources, agricultural products (such as grain containing starch or wild plants, wood containing cellulose, bamboo, reed, straw, etc.).

2.The basic material: the processing of materials, calcium carbide and the above listed all kinds of organic and inorganic materials.

3.Intermediate materials: refers to the complex organic chemical production, with the basic materials produced by the product, but is not the ultimate application of the product, but also need to be further processed, the production of dyes, plastics and drugs of various organic compounds: methanol, acetone, vinyl chloride, etc.
