| Abstract: | The synthesis of n amyl acetate using SnO as catalyst has been studied.The factors influencing the synthesis and the mechanism of catalytic esterification by SnO were discussed.The optimum condition is: molar ratio of n pentanol to acetic acid is 1.3∶1,the quantity of catalyst is equal to 1.5% feed stock,the reaction temperature is 128 ℃～134 ℃,and the reaction time is 2.0 h.SnO is an excellent catalyst for synthetizing n amyl acetate and its yield can reach over 65.2%. |
