| Abstract: | Methyl Chloroacetate is produced by the reaction of chloroacetic acid on methylic alcohol in the presence of esterification catalyst sulfuric acid. The influence of molar ratio of raw materials,reaction time,reaction temperature and the amount of catalyst on reaction yield has been discussed. The best technological condition of esterification reaction has been found. The dynamic method is effective in the increase of the yield of esterification reaction. The yield of methyl chloroacetate amounts to 72. 3% when this dynamic method is used. |
