2,4-dihydroxybenzopenone%n-octylchloride%UV-531%Synthesis%UV-absorber
简单介绍了UV-531传统的合成方法，目前合成UV-531的方法（非溶剂法），即以PEG-400为催化剂，氯代正辛烷与2，4-二羟基二苯甲酮在180℃反应6小时后经水洗，高真空蒸馏，切片得到UV-531。
簡單介紹瞭UV-531傳統的閤成方法，目前閤成UV-531的方法（非溶劑法），即以PEG-400為催化劑，氯代正辛烷與2，4-二羥基二苯甲酮在180℃反應6小時後經水洗，高真空蒸餾，切片得到UV-531。

The common synthesis method of UV-531 were simply introduced in this paper.At the same time the synthesis method of UV-531 (the not solvent method)were discussed indetail nowadays.By using PEG-400 as catalysis,n-octylchloride and 2,4-dihydroxybenzopenone were reacted for 6h at 180℃.Then UV-531 were formed by washing,distillation by high vacuum,slice processing .
