Dimethylformamide (DMF) is a transparent liquid that can be soluble with water and most organic solvents and is a common solvent for chemical reactions. Pure dimethylformamide is odorless, but industrial or deteriorated dimethylformamide has a fishy smell because of impurities. The name of dimethylformamide comes from the fact that it is a dimethyl substitute of formamide (amide of formic acid), and both methyl groups are located on the N (nitrogen) atom. Dimethylformamide is a polar (hydrophilic) nonprotonic solvent with high boiling point, which can promote the SN2 mechanism chemical reactions. Dimethylformamide is synthesized by the reaction of formic acid and dimethylamine. Dimethylformamide is unstable in the presence of strong bases, such as sodium hydroxide or strong acids such as hydrochloric acid or sulfuric acid (especially at high temperatures), and it hydrolyzes to formic acid and dimethylamine.
The explosion limit of steam-air mixture is 2.2-15.2%. It is miscible with water and ordinary organic solvents, and the mixture layered when mix with petroleum ether. When exposed to open fire and high temperature, dimethylformamide can cause combustion and explosion. It can react violently with concentrated sulfuric acid, fuming nitric acid and even explode. Hazard mark 7 (flammable liquid).
Application for the DMF
Dimethylformamide is not only a chemical raw material with wide use, but also an excellent solvent widely used. It can be used for wet spinning of synthetic fibers such as polyacrylonitrile fibers, synthesis of polyurethane, plastic film making, or as Paint stripper. It can also dissolve some low solubility pigments, so that the pigments have the characteristics of dyes.
In petrochemical industry, it can be used as a gas absorbent and chlordimeform. In the pharmaceutical chemical industry, it can be used to synthetize iodopyrimidine, doxycycline, cortisone, vitamin B6, iodine glycoside, vermicular repellent, thiazide, N-methyl-acyl sarcomatolysin, antineoplastic acid, methoxyaromatic mustard, biazanol mustard, cyclohexanone, furosemide, haemostatic acid, betamethasone, methylprogesterone, bile vitamin, chlorpheniramine, etc.
