摘要：

在微波条件下, 系统地研究了催化剂和微波辐射功率对Schiff 碱合成的影响,并和传统搅拌合成方法进行了比较。研究了三种催化剂硫酸氢纳、三氯化铝和三氯化锑对Schiff 碱合成的催化活性。通过红外光谱、核磁氢谱和元素分析等对产品进行结构表征。研究结果表明:反应过程具有反应时间短和反应条件温和的特点;微波辐射功率800?W就可以满足反应条件;路易斯酸三氯化锑比其它的催化剂表现更高的催化活性;催化剂摩尔分数为6％就能明显的促进反应进程。

Abstract:

Compared with the conventional stirring method a study of catalysts and microwave power for the synthesis of Schiff bases under microwave irradiation was performed. In addition, three kinds of catalysts —— NaHSO4, AlCl3 and SbCl3 —— were employed in order to compare their catalytic activities for the synthesis of Schiff Bases. The products were characterized by IR, 1H NMR, and elemental analysis. This demonstrated that the procedure involved a short reaction time and moderate reaction conditions. Microwave power of 800?W was optimum for the reaction, and SbCl3 exhibited higher catalytic activity than the others. 6 mol％ of catalyst was sufficient to accelerate the reaction.

Key words: microwave irradiation; Lewis acid catalyst; SbCl3; Schiff bases
