Product Description
production method : Multi-purpose cyanide esterification method. Chloroacetic acid and sodium carbonate and the formation of sodium chloroacetate, and then cyanide cyanide cyanide sodium cyanate. Sodium cyanoacetate hydrolysis into sodium malonate, and then in the presence of sulfuric acid and methanol esterification of dimethyl malonate, after washing, distillation that was finished. Industrial products containing ≥ 98%. Consumption of raw materials fixed: chloroacetic acid 1120kg / t, sodium cyanide 551kg / t, methanol 955kg / t. The new technology developed abroad is mainly catalyzed carbonylation method, namely, chloroacetate, carbon monoxide, methanol as raw material, in the presence of catalyst, one step reaction synthesis of dimethyl malonate. In contrast, catalytic carbonylation process technology is advanced, but the process is complex, the reaction conditions harsh, industrialization has some difficulties.
use
Organic Synthesis. Commonly used in pharmaceutical pipemidic acid intermediates and spices intermediates, pesticide intermediates.
