微波辐射相转移催化肉桂酸苄酯的合成

Synthesis of Benzyl Cinnamate Catalyzed by PTCs Under Microwave Irradiation

研究了以肉桂酸钠和氯化苄为原料,采用微波辐射技术,分别以四丁基溴化铵(TBAB)、四丁基氯化铵(TBAB)、十六烷基三甲基溴化铵(HTAB)、十六烷基三甲基氯化铵(HTAC)、苄基三乙基氯化铵(TEBA)为相转移催化剂催化合成肉桂酸苄酯,并且讨论了各催化剂的用量、微波辐射功率、辐射时间对酯产率的影响.

With sodium cinnamate and benzyl chloride as raw material, tetrabutylammonium bromide(TBAB), tetrabutylammonium chloride (TBAC), hexadecy trimethylammonium bromide (HTAB) hexadecy trimethylammonium chloride (HTAC) and benzyltriethylammonium chloride(TEBA) as catalyst, benzyl cinnamate was synthesized directly under normal pressure and microwave irradiation. The effects of amount of catalyst, power and time of microwave irradiation on yield were studied.
