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 various high polymers such as polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, etc., and can be used for wet spinning of synthetic fibers such as polyacrylonitrile fibers and synthesis of polyurethane; It is used for making plastic films; it can also be used as a paint remover for removing paint; it can also dissolve some low-solubility pigments, making the pigments have the characteristics of dyes. Dimethylformamide is used for the extraction of aromatics 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, and solvent extraction or partial Crystallization can separate the two. 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 chlordimeform; in the pharmaceutical industry, it can be used to synthesize iodopyrimidine, doxycycline, cortisone, vitamin B6, iodine glycoside, repellent, pyrantel, N-formyl sarcoid, anti Oncosine, methoxymustine, carmustine, cyclohexylnitrosourea, furofluorouracil, tranexamic acid, befenmethasone, megestrol, cholerita, chlorpheniramine and so on. Dimethylformamide has a catalytic effect in the reactions of hydrogenation, dehydrogenation, dehydration and dehydrohalogenation, which reduces the reaction temperature and improves the purity of the product.
