Toluene is widely used as a solvent and an additive for gasoline with high octane number. It is also an important raw material for organic chemical industry. However, compared with benzene and xylene obtained from coal and petroleum, the current output is relatively excessive. Therefore, a considerable amount of toluene is used for dealkylation to benzene or disproportionation to xylene. A series of intermediates derived from toluene are widely used in dyes; Medicine; pesticides; Explosives; auxiliary; The production of fine chemicals such as spices is also used in the synthetic material industry.

Electroless plating, as a new metal surface treatment process, has been widely used in many fields, and has attracted more and more attention because of its energy-saving, environmental protection and simple process. In terms of protection performance, it can improve the corrosion resistance and service life of the workpiece; In terms of functionality, it can improve the wear resistance, conductivity, lubrication and other special functions of machined parts, so it has also become a hot spot of surface treatment technology.

Direct esterification is the main process for the industrial production of ethyl acetate in China. Ethyl acetate was directly esterified with acetic acid and ethanol as raw materials and sulfuric acid as catalyst, and then dehydrated and refined by fractional distillation.

It is widely used as an organic raw material and solvent. As chemical raw materials, it can produce acetone, hydrogen peroxide, methyl isobutyl ketone, diisobutyl ketone, isopropylamine, isopropyl ether, isopropyl alcohol ether, isopropyl chloride, as well as isopropyl esters of fatty acids and chlorinated fatty acids. In fine chemicals, it can be used to produce isopropyl nitrate, isopropyl xanthate, triisopropyl phosphite, aluminum triisopropoxide, medicines and pesticides.
