Catalytic synthesis of n-amyl acetate by heteropoly acid |
| |
| Abstract: | The esterification of acetic acid and n amyl alcohol by using heteropoly acid as catalyst was studied.Effects of catalyst preparation,raw material ratio,reaction temperature and time,the type and amount of catalyst used on the ester yield was investigated.Heteropoly acid as catalyst,moderate condition of reaction,small amount of catalyst with high catalytic activity,non corrosive to the equipment and little,pollution from the reaction were the advantage.At optimal reaction conditions,the ester yield reached 98.55%.Experiments showed that heteropoly acid is a promising catalyst in n amyl acetate synthesis. |
