摘　　要：在正丁醛和乙酰乙酸乙酯为原料合成芹菜酮的合成过程中,对其催化方法进行改进。首次采用K2O/γ-Al2O3型固体超强碱催化合成的工艺路线,考察了催化剂的焙烧温度、合成反应温度、催化剂用量、反应物的量比对转化率的影响,确定了最优化的反应条件,缩短了反应时间,提高了产物的收率。该催化剂具有较高的催化活性,易于回收,能够重复利用五次以上。The synthesis of celery ketone from butyl aldehyde and ethyl acetoacetate was improved with higher yield by using solid superbase（K2O/γ-Al2O3） for the first time. The factors affecting the condensation yield were investigated, the optimum conditions of catalyst calcinations temperature, reaction temperature of synthesis, catalyst dosage, the proportion of reactant, ascertain of reaction condition of excellence and cut down of reaction time. The catalyst can be recovered and reused for more than five times.
