摘　　要：本文介绍了紫外线吸收剂UV-531的性质，比较了各种制备方法，结果表明，使氯代正辛烷在相转移催化剂存在下与2，4-二羟基二苯酮反应合成UV-531的方法适于工业化生产。In this paper,the property of ultraviolet absorbers UV--531 was introduced in Detail. At the same time the different preparation method were compared. The results showed that A process for preparaing UV--531 by alkylation 2,4--dihydroxy benzophenone with n--oetylchlorid in an aqueous solution of an alkali metal hydroxide in the presence of the phase transition catalyst had strong technical superiority.
