Progress in the Research of Solid Superacid Catalysts for the Synthesis of Esters

Solid superacids have been widely studied as catalysts for the synthesis of esters in recent years. The merits of solid superacids are notable as esterification catalysts to substitute concentrated sulfuric acid. In this paper, the use and research status of solid superacid catalysts in the synthesis of esters and the progress in the research of pillared interlayer clay catalysts and clay solid superacid catalysts prepared by meliorating PILC catalysts were introduced.
