摘要
苯酚与邻烯丙基苯酚在催化剂作用下，发生ＦｒｉｅｄｅｌＣｒａｆｔｓ烷基化反应，生成双酚化合物１，２二（２羟基苯基）丙烷（Ⅰ）和１（２羟基苯基）２（４羟基苯基）丙烷（Ⅱ）的混和物（简称双酚Ｐ）．考察了催化剂对该反应的产率和产物中（Ⅰ）／（Ⅱ）比例的影响．选择产率较高和产物中（Ⅱ）比例较大的硅钨酸为催化剂，经正交试验法确定了最佳反应条件，产率达到８４５％．
A mixture of bisphenol was obtained through Friedel Crafts alkylation of phenol with o allyl phenol.This bisphenol mixture(named bisphenol P)was mainly composed of 1,2 bis(2 hydroxyphenyl)propane and 1 (2 hydroxyphenyl) 2 (4 hydroxyphenyl)propane.The influence of catalyst on the yield of bisphenol P and the ratio of ortho isomers to para isomers was investigated.By orthogonal design,the optimum condition of preparing bisphenol P was given.Silicotungstic acid was chosen as catalyst according to the high yield and high proportion of para isomer.
