| Abstract: | The synthesis of tridecane dicarboxylic acid diethyl ester with ethyl alcohol and tridecane dicarboxylic acid as reactants and cation exchange resin as catalyst had been studied.The influence factors of reaction were investigated.The result showed that the appropriate condition should be :with the removal of water on 3 molecular sieve,mole ratio of alcohol to tridecane dicarboxylic acid was 4∶1;the amount of catalysts was 2%of tridecane dicarboxylic acid and the reaction time was 7 h.The yield of esterification was about 98.4%,and the catalyst can be reused three times. |
