Product Details

N,N-Dimethylacetamide CAS# 64-17-5

N,N-Dimethylacetamide is a highly polar aprotic solvent, micro ammonia odor, very strong dissolving power, soluble wide, miscible with water, aromatics, esters, ketones, alcohols, ether, benzene and chloroform and other arbitrary and enable activation of molecular compounds. It is widely used as a solvent and a catalyst. The solvent, with high boiling point, flash point, thermal stability and chemical stability of the solvent, is used for polyacrylonitrile spinning solvent, synthetic resin and natural resins, formic acid vinyl ester resin, vinyl pyridine copolymer and aromatic carboxylic acid. The catalyst can be used in the process of urea heating to produce the reaction of cyanide, sodium halide and metal cyanide to produce the reaction of alkyl acetylene, organic halide and isocyanate. N,N-dimethylacetamide also can be used as electrolytic solvent and photography with coupler solvent, de paint agent, organic synthesis of raw materials, pesticide and pharmaceutical raw materials. Separation of styrene from C8 fraction, extraction, distillation, solvent, etc.

Product Usage

The propanols are used generally as solvents for coatings; in antifreeze compositions and family and private products; and as chemical intermediates for the manufacturing of esters, amines, and different natural derivatives. As a solvent, 1-propanol is used basically in printing inks, paint, cosmetics, pesticides, cellulose esters and insecticides.

1-Propanol is used commercially to produce glycol ethers. These are characterised by using twin functionality, which imparts high solvency, chemical stability, and water compatibility.
