| 摘 要： | Different Michael addition reactions catalyzed by solid base K2O/γ-Al2O3 and KF/γ-Al2O3, MgO/γ-Al2O3 prepared by microwave irradiation method were reported in this paper. For the K2O/γ-Al2O3, not only good yield was attained but also made the reaction of Acetonitrile that usually is regarded as inactive carbonion and α, β-unsatumted compound to carry out. The yield of Michael reaction of Ethyl acetoacetate and Crotonaldehyde catalyzed by KF/γ-Al2O3, MgO/γ-Al2O3, MgO/NaY all could reach to 80% and the latter could reach to 90%. At the same time, the catalysts of different content(the ratio of load) of MgO were also applied in this reaction, and it was found that the best content of MgO was 20% ～ 25%。
