| 摘 要： | 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 soild-supported H3PO4.By comparison of the acylation reactions of 2,3-dimethyl-2-butene with acetic anhydride over various soilds-supported H3PO4,it was found that K10 clay,silicagel,HY zeolite and HMordenite were good supports.The results obtined indicate that the soild-supported small amounts of H3PO4 possessed higher catalytic activities,For obatining a higher yield of 3,3,4-trimethyl-4-penten-2-one different supports required different modification methods.

| 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 solid|supported H-3PO-4. By comparison of the acylation reactions of 2,3|dimethyl|2|butene with acetic anhydride over various solids|supported H-3PO-4, it was found that K10 clay, silica gel, HY zeolite and H|Mordenite were good supports. The results obtained indicate that the solid|supported small amounts of H-3PO-4 possessed higher catalytic activities. For obtaining a higher yield of 3,3,4|trimethyl|4|penten|2|one different supports required different modification methods. |
