| Abstract: | It is reported in this paper that aldehydes or ketones were condensed with amines on the alumina supporter irradiated by microwave.Both the effects of microwave power and time on the reaction were investigated.The reaction temperature was realized when the low polarity and melting point rising in sequence materials had been installed in capillary vessels.Compared with the conventional without solvent or microwave,this increased considerably the reaction rate and yield.The mechanics of microwave irradiation catalyzing this reaction was thought to be related to hydrogen bond and association in intermolecular. |
