Stady on new process for catalytic synthesis of ethyl chloroacetate with solid super strong acid |
| |
| Abstract: | Solid super acid was used as the catalyst for the synthesis of ethyl chloroacetate,using the methods of non water carring agent and multiple adding of alcohol.The total yield was up to 98.8%,which was maintained almost at the same level during the scaling up of the experiments. The results showed that the optimum conditons of esterification are as follows:the amount of solid super acid catalyst is 1.2% of total mass of reactants,the molar ratio of acid to alcohol is 1.0∶6.6,the reaction time is 5～6 h,adding alcohol in multiple time with the reaction proceeding. |
