Progress on the Research of Solid Superacid Catalysts

Abstract : Effect of the preparation conditions on properties of Mx0y/S042- type of solid superacid and the ef-fect of catalysis in esterification reactions are discussed, the advantages and defects of the catalysts MxOy/ S042 ~ solid superacid in esterification reactions are analysed. It is pointed out that composite superacid catalysts will be the main direction.
