摘要: 以50 %(质量分数,下同)乙醛酸水溶液(乙醛酸)和2,4-二叔丁基苯酚(烷基酚)为起始物,采用“酯化加成-烷基化-萃取结晶”的工艺路线合成了3-芳基苯并呋喃酮类化合物3-(3,4-二甲基苯基)-5,7-二叔丁基-3-氢苯并呋喃-2-酮(SHY-1)。全面系统地考查了反应温度、时间、压力、原料配比、催化剂及其用量等条件对产物收率的影响,并采用红外光谱、质谱、核磁共振及元素分析等方法对目标产物进行了分析。结果表明,酯化加成反应的乙醛酸与烷基酚摩尔比为1.3:1、反应温度为100 ℃、反应时间为3 h,烷基化反应的催化剂用量与烷基酚质量比为0.12:1、反应压力为-0.06 MPa、反应时间为2.5 h时,目标产物收率可达70.2 %。

Abstract: Starting from 50ω% aqueous glyoxylic acid and 2,4-di-tert-butylphenol,synthesized 3-(3,4-dimethylphenyl)-5,7-di-tert-butyl-methyl-3H-benzofuran-2-one by" process esterification addition - alkylation- extractive crystallization", and studied the effects of process parameters on the yield of the target product comprehensively and systematically. The synthesis reaction conditions were optimized, the yield of target product reaches 70.2% when the molar ratio of glyoxylic acid and alkylphenol equales to 1.3:1, at 100℃, reaction 3h, in esterification addition reaction, and when the molar ratio of catalyst to alkylphenol is 0.12:1, at -0.06MPa, reaction 2.5h, in alkylation.
