What Is The Role Of Chemical Raw Materials

There are many kinds of chemical raw materials, which are widely used. There are as many as 5-7 million kinds of chemicals in the world, and more than 100,000 kinds are sold and circulated in the market, and more than 1,000 new chemicals are released every year, and 150-200 of them are considered to be carcinogenic. thing.

Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic 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, organic acids, carboxylic acids Salts, Carbohydrates, Heterocycles, Nitriles, Halogens, Aminoamides, Others

Inorganic chemical raw materials

The main raw materials of inorganic chemical products are chemical minerals such as sulfur, sodium, phosphorus, potassium, and calcium (see inorganic salt industry), coal, oil, 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 recovered by sulfuric acid to produce ammonium sulfate, chalcopyrite, galena The sulfur dioxide in the smelting exhaust gas of ore and sphalerite can be used to produce sulfuric acid, etc.

Dangerous goods are generally the raw materials, intermediates and products of the chemical industry. The choice of transportation method is mainly based on the physical and chemical properties of the relevant products. If it is a production, trade or logistics enterprise, it needs to transport dangerous goods. The MSDS (Material Data Safety Sheet) of the product, the product is divided into three states: solid, liquid and gas, the solid state is generally only transported by a pallet truck, the gaseous state can only be stored in a pressure cylinder or a pressure tank, and the liquid product is flexibly transported, because it is closely related to temperature. There are the following options for its transportation: general barreled rear fence trucks with high viscosity or thermal insulation heating tank trucks; chemicals with viscosity close to water, low vapor pressure, and non-corrosive chemicals are transported by general pressure tankers; there are Corroded products can be transported in stainless steel tankers.
