摘　　要：对文献报道的制备方法进行了改进。在激烈搅拌下将液溴滴加至等摩尔量的二氧六环中,直至完全固化,用乙醚溶解固体产物,再同苯酚进行溴化反应,同时考察了反应条件对反应的影响。反应产物以对澳苯酚为主,其最高收率可达91.4%。Dioxane-dibromide is a moderate reagent used for bromination.We have modified itspreparation method developed by Billimoria.Themodified reagent is allowed to react with phenolin ether.This bromination was studied underdifferent reacting temperatures,volumes of etherand three ways of addition sequences.The experi-ment results showed that p-bromophenol wasthe major product of the reaction with the ma-ximum yield as high as 91.4%.
