Buy N,N-Dimethylacetamide (DMAC solvent) at factory price from TNJ Chemical

N,N-Dimethylacetamide DMAC is very similar to N,N-Dimethylformamide, is a representative of amide solvents. When there is no acid and alkali, it can be heated to the boiling point under normal pressure but no discompose, so that it can be distilled at atmospheric pressure. The hydrolysis rate is very slow, containing 5% water of N,N-Dimethylacetamide DMAC at 95 C heating for 140 hours, only 0.02% hydrolysis occurred. But when the acid base exists, the hydrolysis rate increases. The presence of alkali would make saponification when heating; But when heated in the presence of H+, it will occur alcoholysis reaction.

 

Production method

TNJ Chemical adopted synthesis of acetic acid and methylamine method, and achieved good results. This process is characterized by the use of advanced catalytic reaction distillation technology, so that the reaction can be strengthened, and to reduce energy consumption, separation efficiency and product yield is greatly improved, process simplification. Compared to the synthesis process of acetic anhydride method, reduce production costs, improve economic efficiency.

 

Usage & Application

1.DMAC is mainly used as synthetic fiber (acrylonitrile) and polyurethane spinning and synthetic polyamide resin is used for solvent, extractive distillation solvent separation styrene from C8 fraction, and is widely used in polymer film coating and medicine and so on. At present, in medicine and pesticide amount used for synthesis of antibiotics and pesticide. 

2 used as catalyst for reaction; electrolytic solvent; paint remover and a variety of crystalline solvent adduct and complex. 

3 used as solvent, paint remover, catalyst and organic synthesis.
