摘　　要：介绍了紫外线吸收剂UV-531传统的几种合成方法,报道了用低成本合成UV-531的方法(非溶剂法),即以PEG-400为催化剂,不加任何溶剂条件下氯代正辛烷与2,4-二羟基二苯甲酮在180℃反应6h后经水洗,高真空蒸馏,切片得到成品。The common synthesis of UV-531 was simply introduced in this paper. At the same time the new synthetic method without solvent was discussed in detail nowadays. By using PEG-400 as catalyst,n-octylchloride and 2,4-dihydroxybenzopenone reacted for 6 h at 180 ℃ to form UV-531 following the washing,distillation by high vacuum and slice procedures.
