Abstract: It is proved by the experiment that HPAis a good catalyst for the reaction of toluene sulfonation to 4,4'-dimethyldiphenyl sulfone.The effect of HPAon p-methyl sulfonic acid has been studied by means of UVand variable-temperature 1H NMR.The preliminary catalytic mechnism is also proposed.

Key words: Heteropoly acid, Toluene, Sulfonation, 4,4'-Dimethyldiphenyl sulfone
