product details:
Dimethyl Formamide (DMF) is a colorless and transparent liquid, which is miscible with water and most organic solvents. Pure dimethylformamide has a special odor, and industrial grade or deteriorated dimethylformamide has a fishy smell because it contains impurities of dimethylamine.
The source of the name is that it is the dimethyl substituent of formamide (the amide of formic acid), and both methyl groups are located on the N (nitrogen) atom. It is a common solvent for chemical reactions.
As a polar (hydrophilic) aprotic solvent with a high boiling point, it can promote the SN2 reaction mechanism. Dimethylformamide is manufactured using methyl formate and dimethylamine.

Application:
Dimethylformamide is not only a widely used chemical raw material, but also an excellent solvent.
Dimethylformamide is a good solvent for many kinds of polymers, such as polyethylene, polyvinyl chloride, polyacrylonitrile and polyamide. It can be used for wet spinning of polyacrylonitrile fiber and synthesis of polyurethane; Used for making plastic film; It can also be used as paint remover; It can also dissolve some pigments with low solubility, so that the pigment has the characteristics of dye.
Dimethylformamide is used for aromatics extraction, butadiene recovery from C4 fraction, isoprene recovery from C5 fraction, and non hydrocarbon separation from paraffin. It has good selectivity for the solubility of isophthalic acid and terephthalic acid: the solubility of isophthalic acid in dimethylformamide is higher than that of terephthalic acid, which can be separated by solvent extraction or partial crystallization in dimethylformamide. In petrochemical industry, dimethylformamide can be used as gas absorbent to separate and refine gas. In organic reactions, dimethylformamide is not only widely used as a solvent, but also an important intermediate in organic synthesis.
