摘　　要：以3,5-二叔丁基-4-羟基苯甲酸为原料,采用还原法制备了3,5-二叔丁基-4-羟基苯甲醇。结果表明,当n(羧酸)∶n(ZnCl_(2))∶n(NaBH4)为1.0∶1.5∶2.5时,以四氢呋喃为溶剂,在温度65℃条件下,转化率为98.5%。The synthesis of 3,5-di-tert-butyl-4-hydroxybenzyl alcohol by reduction method using 3,5-di-tert-butyl-4-hydroxybenzoic acid as the raw material was investigated.Experiment results show that the conversion rate can reach 98.5%at 65℃when n(carboxylic acid)∶n(ZnCl_(2))∶n(NaBH4)is 1.0∶1.5∶2.5 and tetrahydrofuran is used as solvent.
