| Abstract: | In this article, the interaction between HPA catalyst and arenesulfonic acid is studied by means of variable-temperature 1H NMR. The mechanism of HPA catalyzing the reactions for sulfonating aromatic compounds to aryl sulphone is proposed. The proton from HPA plays a main role in these reactions and HPAN has influence over the reaction rate and selectivity. |
