【Abstract】 The supported Fe 3+ 732 resin catalyst was syntheized.Fe 3+ 732 resin has different activity from that of non suppoted 732 resin in this reactions.The influence on activity of catalyst in the reactions of benzene hydroxylation to phenol by exchange method,acid washing and iron content was investigated.As a result,the most favourable one in improving catalytic activity is using acid washing,dynamic exchange method.Optimal phenol yielding rate can reach about 77%.The iron content of catalyst is 79.29 mg per one gram dry resin.更多还原
