摘　　要：采用对甲苯磺酰氯和正辛醇为起始原料,先制备对甲苯磺酸正辛酯,再将其与2,4-二羟基二苯甲酮反应合成产物UV-531。研究了碱、温度、对甲苯磺酸正辛酯与2,4-二羟基二苯甲酮物质的量比对反应收率的影响。结果表明最优的反应条件是碳酸钾为碱,反应温度为80℃,对甲苯磺酸正辛酯与2,4-二羟基二苯甲酮物质的量比为1∶1.1,UV-531的收率为96.2%。The reaction of 1-octanol with tosyl chloride afforded p-octyl toluenesulfonate,which subsequently reacted with 2,4-dihydroxybenzophenone to form product UV-531.Various bases,temperature and the molar ratio of 2,4-dihydroxybenzophenone to p-octyl toluenesulfonate were examined.When the molar ratio of 2,4-dihydroxybenzophenone to p-octyl toluenesulfonate is 1∶1.1,the maximum yield of product UV-531 can reach 96.2%using K 2CO 3 as a base under 80℃.
