Direct esterification of succinic acid with phenol in the presence of zeolite catalysts was explored. H⁺-zeolite β (SiO₂/Al₂O₃ = 150) has emerged as the most effective solid acid catalyst, affording 96% yield of diphenyl succinate. The catalyst could be recycled upon 5 consecutive runs without appreciable decreases in activity. Additionally, the catalyst was successfully applied to the esterification of several dicarboxylic acids with phenol producing good and moderate yields of the desired products. The proposed method not only offers essential features of the heterogeneous systems but also brings simplicity in operation, makes it more economical and environmentally-friendly.

探索了在沸石催化剂存在下琥珀酸与苯酚的直接酯化。H ⁺沸石β（SiO ₂ / Al ₂ O ₃  = 150）成为最有效的固体酸催化剂，琥珀酸二苯酯的收率达96％。该催化剂可以连续运行5次而没有明显降低活性的情况下进行再循环。另外，该催化剂成功地用于几种二元羧酸与苯酚的酯化反应，产生了所需产品的良好和中等收率。所提出的方法不仅提供了异构系统的基本特征，而且使操作简单，使其更加经济和环保。
