摘　　要：对杂多酸和固载型杂多酸催化剂催化α -萘乙酸和甲醇反应合成α -萘乙酸甲酯进行了研究。探讨了催化剂用量、醇酸摩尔比、反应时间等因素对反应结果的影响 ,得到了较适宜的反应条件。固载型杂多酸催化剂可多次使用而活性没有明显下降。Heteropoly acids-catalyzed esterification between α-naphthylacetic acid and methanol was studied.Non-supported and supported catalysts with hihg activity and selectivity were selected.The effects of reaction conditions such as amount of catalysts,alcohol-acid ration,reaction time were investigated.The most suitable condition for the reaction was obtained.The supported catalyst could be used for several times without distinct decrease in activity.
