Preparation and Catalytic Application of Phenylsulfonic Acid Functionalized Porous Phosphate Heterostructure Materials
A series of phenylsulfonic acid functionalized porous phosphate heterostructure (PPH) materials were prepared by co-condensation method and characterized by SEM, FHR, Si MAS NMR, TG and N2 adorption. Their catalytic behavior for alkylation of hydroquinone with tert—butanol was compared. The catalytic activity was greatly enhanced after the introduction of phenylsulfonic acid group. ZrP-0.4-2-10%-PhSO3 H is a more active catalyst for the reaction in comparison to others. The conversion of hydroquinone and the yield of 2-tert-butylhydroquinone on the catalyst reach 85.4% and 58.5% at 150°C, respectively. The activity correlates well with the amount of the accessible acid sites on its surface. The catalyst is stable and reusable, and the product yield is only reduced by 10% after three runs. The reduction in activity is probably caused by leaching of phenylsulfonic group or deposition of coke on the active sites.
