| 摘 要： | 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、Synclyst S13(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。

| Abstract: | 3,3,4-Trimethyl 4 penten 2 one has been synthesized by the acylation of 2,3 dimethyl 2 butene with acetic anhydride in the presence of zinc chloride supported on various solids. K10 clay was the best support, but HY zeolite, Synclyst S13(an amorphous acidic solid), silica gel and alumina were all reasonable supports. Both the loading of ZnCl 2 and the modification method affected the catalytic activity of the catalysts. |
