| Abstract: | Heteropoly acid supported on bentonite was prepared by saturation impregnation and used as catalyst for synthesis of ethyl heptanoate.The effects of the sticking of heteropoly acid by catalyst,the quantity of catalyst,reaction time and the repeated use of catalyst on reaction were discussed.The optimal reaction conditions were as follows:the optimal concentration of acid-treated bentonite 30%,the amount of the catalyst 3.5% of heptylate used,reaction time 3 h,reaction temperature 80~88 ℃. |
| Keywords: | bentonite heteropoly acid esterification ethyl heptanoate |
