乙酰丙酮与芳香胺单Schiff碱的合成

THE SYNTHESES OF MONOARYLAMINE SCHIFF BASES OF ACETYLACETONE

用分水器分水与苯或甲苯恒沸脱水相结合的方法,以浓盐酸或对甲苯磺酸作催化剂,系统地研究了乙酰丙酮与芳香胺单Schiff碱的合成;制备出六个相应的Schiff碱,产率高达60%～87%.

This paper researched systematically the syntheses of monoarylamine Schiff bases of acetylacetone by using a new dehydrating method-water knockout trap dehydrating combined with benzene or toluene constant distilling dehydrating. Under the catalysis of concentrating HC1 or p-toluene salfonic acid- six Schiff bases were preparedi the yields were 60%-87%
