稀土固体超强酸催化合成对羟基苯甲酸酯

The Study of Rare Earth Solid Superacids for Catalytic Synthesis of Hydroxybenzoic Ethers

制备了一系列稀土固体超强酸 ,用于催化合成对羟基苯甲酸酯 .研究了稀土固体超强酸的催化性能 ,同时研究了反应的条件 .结果表明 ,这些催化剂基本上都有较高的催化活性 ,且性能稳定 。

In this paper,a series of rare earth solid superacids we re prepared and used for synthesizing hydroxybenzoic ethers,and their catalytic properties in the esterification were examined.In the meantime the effects of reactive conditions on the esterification were examined.It was found that these rare earth solid superacids showed higher catalytic active on the whole and sta bility and can be reused.
