Preparation of Methyl cyanoacetate: it can be prepared by cyanoethylolmethoxycarbonyl and sodium cyanide. Add sodium cyanide, methanol and solvent PTC into the reactor at first. Then heat it to 55 °C with stirring. Next, add cyanoethylolmethoxycarbonyl into yhe mixture in 15 minutes with stirring. The reaction should react for 3 hours. At last, through a series of filtration, distillation and vacuum distillation you can get the desired product.
Uses of Methyl cyanoacetate: it can react with benzaldehyde to get 2-cyano-3t-phenyl-acrylic acid methyl ester. This reaction will need catalyst natural phosphate and solvent methanol. The reaction time is 15 minutes at reaction temperature of 20 °C. The yield is about 85%.
