| Abstract: | The esterification reaction between adipic acid and 1-octyl alcohol catalyzed by heteropoly acid is studied . The number of non-supported and supported catalysts with high activity and selectivity are select- ed. The effects of reaction conditions are investigated. The most suitable conditions for the reaction are as follows:molar ratio of acid to alcohol 1:2.4,mass ratio of catalyst to adipic acid 1.4% ,reaction time 3.5h. The conversion of adipic acid and the selectivity for di-1-octyl adipate are over 99% . The supported catalysts can be used for several times without distinct decrease in activity. |
