摘　　要：利用均苯三酚和对羟基苯乙酸为原料,新蒸馏三氟化硼乙醚为催化剂和溶剂,"一锅法"合成2,4,6,4′-四羟基脱氧安息香;通过改进工艺条件;均苯三酚与对羟基苯乙酸摩尔比为5.1∶5,25°C条件下,反应3.5 h产率达到60%以上。The optimal synthesis conditions were found. 2,4,6,4t-Tetrahydroxydeoxybenzoin in yield of more than 60% was synthesized by using ＂one pot＂ method. The ratio of 1,3, 5-benzenetriol to 4- hydroxyphenyl was 5. 1 ： 5, newly distilled boron trifluoride ethylether complex was used as solvent and catalyst, and the reaction was run at 25℃ for 3.5 h under reflux.
