Production of Diethyl Malonate

Posted in General | 11:15

The mainly production methods of Diethyl malonate is cyanide esterification method and catalytic carbonylation method. At present, it is still widely accepted traditional cyanide esterification method. Chloroacetic acid by xylitol, esterification, hydrolysis, and cyanide.Chloroacetic acid generated in the 30 ° c with sodium carbonate and sodium CHLOROACETATE, at 92-95 with sodium cyanide, cyanide, and alkaline hydrolysis of sodium malonate. Malonic acid sodium after drying in the presence of sulfuric acid esterification with ethanol in 70-72 ℃. The esterification products after washing, distilling to finished product, diethyl malonate. Abroad to develop new technology mainly catalytic carbonylation method, namely the chloroacetic acid ester, carbon monoxide, ethanol as raw material, the catalyst is the next step reaction synthesis of diethyl malonate.
