Dimethylformamide is not only a very widely used chemical raw material, but also a very widely used excellent solvent. Dimethylformamide is a good solvent for many polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc. It can be used for wet spinning of synthetic fibers such as polyacrylonitrile fibers and synthesis of polyurethane. Used for plastic film making; Can also be used to remove paint stripper; It can also dissolve some low solubility pigments, so that the pigment has the characteristics of dyes. Dimethylformamide is used for the extraction of aromatics and for the separation and recovery of butadiene from C-4 fractions and isoprene from C-5 fractions. It is also 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: isophthalic acid is more soluble in dimethylformamide than terephthalic acid, and can separate the two by solvent extraction or partial crystallization in dimethylformamide. In the petrochemical industry, dimethylformamide is used as a gas absorber to separate and refine gases. In organic reactions, dimethylformamide is not only widely used as a solvent, but also an important intermediate in organic synthesis. It can be used to produce chloramidine in the pesticide industry; In the pharmaceutical industry, it can be used to synthesize iodimidine, doxycycline, cortisone, vitamin B6, iodoside, pamodil, thiacil, N-formylsarcomysin, antitumine, methoxyluridine, benazine, cyclohexanitrourea, fururacil, styptic acid, befenamethasone, megestrol, bilviuta, pramine and so on. Dimethylformamide plays a catalytic role in hydrogenation, dehydrogenation, dehydration and dehalogenation reactions, which reduces reaction temperature and improves product purity.
