| Abstract: | Methylacrylic acid 16 ester was synthesized by aqueous solution polymerization with toluene as water-carrying agent.The various synthetic methods were discussed.The degree of esterification was confirmed by measuring the acid value of esterified ester.The purification and separation method were improved,and the purity of methylacrylic acid 16 ester was increased.The results indicated that when reaction temperature was 110 ℃,molar ratio of acid to alcohol was 1.2∶1,catalyst amount was 2.0%,and reaction time was 5 h,the esterification rate was up to 92%. |
