研究了负载ZnCl2 的固体催化剂在 2 ,3 二甲基 2 丁烯与乙酐酰化合成 3,3,4 三甲基 4 戊烯 2 酮反应中的催化活性。结果表明 ,K10粘土是最好的载体 ,但是HY沸石、SynclystS13(一种无定型的酸性固体 )、硅胶和氧化铝也都是制备负载ZnCl2 的固体催化剂的有效载体。ZnCl2 的负载量和改性方法都影响负载ZnCl2 的固体催化剂的催化活性 The catalytic activity of ZnCl2-supported solid catalysts for the synthesis of 3,3,4-trimethylpentene-2-ketone from 2,3-dimethyl-2-butene and acetic anhydride was studied. The results show that K10 clay is the best carrier, but HY zeolite, Synclyst S13 (an amorphous acidic solid), silica gel and alumina are also both effective carriers for the preparation of ZnCl2-supported solid catalysts. The loading of ZnCl2 and the modification methods both affect the catalytic activity of ZnCl2-supported solid catalysts
