Advance on catalysts for esterification of salicylate

The article discusses the research and development on catalysts for synthesis of salicylate. The functions and characteristic of catalysts have been mainly described for the mixed acids,solid sulfoacids, Lewis acids, heteropolyacids, solid superacids and cationic exchange resin. The result shows that solid supported superacids, heteropolyacids and Lewis acids are goods catalysts for the esterification of salicylate, which have the advantages of high catalytic activity, high reaction selectivity, good atom economy, simple after-treatment, and times reuse of the catalyst. Therefore these catalysts release the good and applied foreground.
