N,N-Dimethylformamide is an excellent organic solvent used as a solvent for polyurethane, polyacrylonitrile, polyvinyl chloride, as well as as a raw material for extractants, pharmaceuticals and pesticides.
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 and polyurethane synthesis of synthetic fibers such as polyacrylonitrile fibers; For plastic film making; It can also be used as a paint stripper to remove paint; It can also dissolve certain low-solubility pigments, giving the pigment the characteristics of a dye. Dimethylformamide is used for aromatic extraction and for the separation and recovery of butadiene from carbon tetra fractions and the separation and recovery of isoprene from carbon penta fractions, and can also be used as an active reagent for the separation of non-hydrocarbon components from paraffin wax. It has good selectivity for the solubility of isophthalic acid and terephthalic acid: isophthalic acid is more soluble in dimethylformamide than in terephthalic acid Chemicalbook, and solvent extraction or partial crystallization in formamide dicarboxylate separates the two. 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 for the reaction, but also an important intermediate in organic synthesis. Pesticide industry can be used to produce insecticidal amidine; In the pharmaceutical industry, it can be used to synthesize iodomin, doxycycline, cortisone, vitamin B6, iodoside, debolacin, thiazimidine, N-formyl lyserolomacin, anti-tumorine, methoxypyrazine, bian nitrogen mustard, cyclohexanniourea, furufluorouracil, hemostatic cyclic acid, becimethasone, megesterone, cholevitamin, chlorpheniramine and so on. Dimethylformamide has a catalytic effect in the reaction of hydrogenation, dehydrogenation, dehydration and dehagenation, which reduces the reaction temperature and improves the purity of the product
