【摘要】 采用微波辐射合成法合成了纳米介孔分子筛MCM-41作为微反应器.以苯并呋喃-2(3H)-酮的合成为实例,在甲苯介质中将邻羟基苯乙酸组装到MCM-41微反应器中,研究了溶液体系及微反应器中反应温度、反应时间及微波辐射时间对反应的影响.结果显示,在施加微波与不施加微波情况下,MCM-41微反应器中进行的反应较溶液体系中进行的反应产率提高了2～33与2～12倍.对于MCM-41微反应器中的反应,施加微波辐射后反应产率可进一步提高20%～100%.更多还原

【Abstract】 MCM-41 mesoporous molecular sieve was synthesized under microwave irradiation and used as microreactor.2-Hydroxyphenylacetic acid was assembled into MCM-41 microreactor in toluene solution,and benzofuran-2(3H)-one was obtained by the intramolecular esterification of 2-hydroxyphenylacetic acid with high selectivity.The reaction conditions including temperature,reaction time,microwave irradiation and so on were investigated.The yield of benzofuran-2(3H)-one was improved by 2～12 and 2～33 times in MCM-41 microreactor than that in solution under conventional heating and microwave irradiation respec-tively.In addition,the yield of the reaction in MCM-41 reactor under microwave irradiation could be im-proved by 20%～100%.更多还原
