N. N-Dimethylacetamide - Preparation
  1. Dimethylamine by acetic anhydride method is acylated with acetic anhydride at 0~20 ℃, and then neutralized with liquid alkali at low temperature to remove acetic acid, and sodium acetate is separated. The neutralized solution is washed with alkali, rectified, and the fraction with boiling range of 164~166.5 ℃ is taken as the finished product.
  2. The acetyl chloride method is obtained by the reaction of dimethylamine and acetyl chloride. Compared with the current domestic acetic anhydride process, this process has lower production cost and higher economic benefits.
