摘要: 对比研究了三氯化铕,三氯化镧,三氯化铈和三氯化镨四种镧系盐催化剂化学选择酯化香草醇收率的影响。以三氯化镧为化学选择催化剂,且香草醇与三氯化镧物质的量比为1:0.005时,癸酸香草醇酯的收率最高为85%,并用该法合成辛酸香草醇酯和月桂酸香草醇酯,其收率分别为87%和71%。

Abstract: The effect of promoters EuCl3, LaCl3, CeCl3 and PrCl3 on the yields of the chemoselective esterifiction of vanillyl alcohol was studied. The results showed that when the molar ratio of vanillyl alcohol/ LaCl3(1:0.005), yields of vanillyl caprylate, vanillyl deaconate and vanillyl dilaurate were as follow 87 percent, 85 percent and 71 percent.
