摘要
用固体超强酸TiO2 /SO2 -4 -沸石分子筛催化合成对羟基苯甲酸酯 ,对催化剂的制备条件和酯的合成反应条件进行了研究 .结果表明 ,该催化剂具有较高的活性 ,并具有一定重复使用性 ,是合成对羟基苯甲酸酯的良好催化剂 。
The synthesis of hydroxybenzoic esters with zeolite supported TiO 2/SO 2- 4 solid super acids as catalysts was proposed in this paper. The preparation conditions of the catalysts and esterification conditions were studied. It was found that the catalyst showed higher catalytic active and can be reused. It showed that the complex catalysts was an excellent for the synthesis of hydroxybenzoic esters.
