Application 

1.Acetonitrile is a raw material for preparing raw acetate, is producing dichloro chrysanthemic acid methyl ester and 2 chloro 2, 3, 3 - trifluoromethyl - 1-tightening allyl 2, 2 - methyl ring propane carboxylic ester (Kung Fu) ester intermediates, and can be used as raw materials to sulfonylurea herbicides intermediate pyrimidine derivatives, and can be used in the manufacture of vitamin B1 in the pharmaceutical industry and in the synthetic rubber industry do C4 fraction extraction agent.
3. For the extraction of nitrile rubber monomer, pharmaceutical and carbon four
4. The main use of acetonitrile is as solvent. Solvent for the synthesis of a solvent for the extraction of butadiene and solvent for the synthetic fiber and for some special coatings. In the oil industry for the removal of tar, phenol and other substances from the petroleum hydrocarbon solvent. In the oil industry as a driven vegetable oil extracting fatty acid solvent, in medicine for steroids drug recrystallization of the reaction medium. In the need of high permittivity of polar solvents often use two yuan of the formation of acetonitrile and water, a total of yuan of boiling mixture: containing acetonitrile 84%, boiling point 76. Acetonitrile is the intermediate of Medicine (vitamin B1), and is the raw material of the production of the three nitrogen and the efficiency of the nitrogen fertilizer. Is also used as an alcoholic. In addition, it can also be used in the synthesis of the synthetic material, such as the synthesis of the material, the acetic acid, etc., and also have many uses in the textile dyeing, the illumination industry.
5. Solvent for most inorganic compounds. Spectrophotometric determination and non water titration solvent. Determination of carboxylic acid as diluent. Heavy crystallization, extraction of fatty acids, etc.. High pressure liquid chromatography (HPLC) solvent.
 
6.Chromatographic analysis of standard substances, solvents and gas chromatographic stationary liquid
