摘　　要：采用介孔分子筛负载杂多酸为催化剂,在釜式反应器内对苯酐和正辛醇的酯化反应进行了研究,考察了催化剂的活性、选择性和稳定性,结果表明,在组成适宜的催化剂和适当的反应条件下,苯酐转化率可达98%,DOP选择性可达100%,且催化剂可重复多次使用。The esterification of anhydride with n - octanol over mesoporous molecular sieves loaded with heteropolyacid was studied. The effects of catalytic activity, selectivity and stability were investigated. The experimental results show that the conversion of anhydride can reach 98% and the selectivity of DOP is 100% under optimum. Moreover the catalyst can be used repetitively.
