Dimethylformamide

1. Used as an analytical reagent and solvent for vinyl resin and acetylene.

2. It is an excellent organic solvent, used as a solvent for polyurethane, polyacrylonitrile, polyvinyl chloride, as an extractant, medicine and raw material for chlorphenamidine pesticide.

3. Dimethylformamide is not only a kind of chemical raw material with a wide range of uses, but also an excellent solvent with a wide range of uses.It can be used in the synthesis of wet spinning and polyurethane of polyacrylonitrile fiber and other synthetic fibers.Used for plastic film making;Can also be used as a paint remover;It also dissolves certain pigments of low solubility, giving them the characteristic properties of dyes.Dimethylformamide can be used for aromatics extraction and for the recovery of butadiene and isoprene from c-4 and C-5 fractions, and as an effective reagent for the separation of non-hydrocarbon components from paraffin.It has a good selectivity for the solubility of m-phthalic acid and terephthalic acid: the solubility of m-phthalic acid in dimethylformamide is higher than that of terephthalic acid, and the two can be separated by solvent extraction or partial crystallization in dimethylformamide.In the petrochemical industry, dimethylformamide can be used as a gas absorber for separating and refining gases.In organic reactions, dimethylformamide is not only widely used as a solvent, but also an important intermediate in organic synthesis.Chlorphenamidine can be produced in the pesticide industry;In the pharmaceutical industry, it can be used to synthesize sulfadiazine, doxycycline, cortisone, vitamin B6, iodide, pinnet, thiacil, N-formyllysosarcoma, antinomine, methoxyl mustard, benzo mustard, cyclohexanilide, furofluorouracil, hemostatic cycloacid, medroxymethamine, medroprogestin, bvidatar, ormin, etc.Dimethylformamide plays a catalytic role in hydrogenation, dehydrogenation, dehydration and dehalation of hydrogen, reducing the reaction temperature and increasing the purity of the product.

4. Non-aqueous titration reagent, solvent for ethylene resin and acetylene, organic synthesis, photometric determination, fixed liquid for gas chromatography (maximum use temperature: 50ºC, solvent: methanol), separation and analysis of C2-C5 hydrocarbon, and separation of positive, isobutene -[1] and cis, reverse butene -[2].Analysis of pesticide residues.Organic synthesis.Synthesis of peptides.For the photographic industry.
