Main use dimethylmethane Amide is an important chemical raw material and a solvent with excellent performance. Dimethylformamide is not only a chemical raw material with a wide range of uses, but also an excellent solvent with a wide range of uses. Dimethylformamide is a good solvent for a variety of polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc., and can be used for wet spinning of synthetic fibers such as polyacrylonitrile fiber and the synthesis of polyurethane. It can also be used as a paint remover for plastic film making. It can also dissolve certain low-solubility pigments, giving the pigments the characteristics of dyes. Dimethylformamide is used for the extraction of aromatic hydrocarbons and for the separation and recovery of butadiene from the C4 fraction and the separation and recovery of isoprene from the C5 fraction. It can also be used as an effective reagent for the separation of non-hydrocarbon components from paraffin. . It has good selectivity for the solubility of isophthalic acid and terephthalic acid. The solubility of isophthalic acid in dimethylformamide is greater than that of terephthalic acid. Solvent extraction or partial crystallization is performed in dimethylformamide. , the two can be separated. In the petrochemical industry, dimethylformamide can be used as a gas absorbent to separate and refine gases. In organic reactions, dimethylformamide is not only widely used as a reaction solvent, but also an important intermediate in organic synthesis. In the pesticide industry, it can be used to produce insecticides. In the pharmaceutical industry, it can be used to synthesize iodine, doxycycline, cortisone, vitamins, iodine glycosides, pyridine, pyrantel, formylsarcolyticin, anti-neoplasmic acid, Methoxychloride, benzene mustard, cyclohexyl nitrosourea, furfururacil, tournexic acid, befenmethane, megestrol, bilevitamin, etc. Dimethylformamide has a catalytic effect in the reactions of hydrogenation, dehydrogenation, dehydration and dehydrohalogenation, lowering the reaction temperature and improving product purity.
