摘要
考察了磷钨酸（Ｈ３ＰＷ１２Ｏ４０·ＸＨ２Ｏ）、对甲基苯磺酸、浓硫酸和ＨＹ型分子筛等四种催化剂对苯酚与邻烯丙基苯酚烷基化反应的影响，结果表明磷钨酸具有较好的催化活性和选择性。在磷钨酸催化下，控制适宜的反应条件，产物产率达７５％，羟值４６７．４。产物经分离及红外光谱、核磁共振谱（Ｈ′－ＮＭＲ）等方法测定，证明主要是１，２－二（２－羟基苯基）丙烷和１－（２－羟基苯基）－２－（４－羟基苯基）丙烷两种双酚的混合物，两种化合物在混合物中比例相近。
The effect of phospho-wolframic acid, toluene sulfonic acid, sulfuric acid and molecular seived HY as catalyst on alkylation from phenol with o-allyl phenol was investigated. The results showed that the catalytical activity and selectivity of phospho-wolframic acid is higher. When phospho-wolframic acid was used as catalyst, the yield of product is 75% and the hydroxyl value is 467.4 at appropriate condition. The product was separated and then determined by IR and H1-NMR. The product is mixture of 1,2-bis(2-hydroxy phenyl) propane and 1-(2-hydroxy phenyl)-2-(4-hydroxy phenyl) propane. The proportion of both compounds is approximately equal in the mixture. The mixture of bisphenols can be used to synthesise monomer of epoxy resin.
