Title
Novel fluorination of polystyrene sulfonic acid resin by CF3SO3H for high stability and strong acidity
Abstract

•Novel and facile fluorinating agent CF3SO3H is used to fluorinate sulfonic polystyrene resin.•The prepared CF3SO2-resin exhibits high stability and acid strength.•The prepared CF3SO2-resin performs well as solid catalyst in the Friedel–Crafts reaction and esterification.

A novel fluorination method derived from CF3SO3H was employed to the polystyrene sulfonic acid resin, to enhance its acid strength and stability. The as-prepared CF3SO2-resin was characterized by FT-IR, XPS, 31P MAS NMR, and chemical titration, and its catalytic performance was tested. It was found that CF3SO2-resin exhibited higher selectivity to benzyltoluene in the Friedel–Crafts alkylation of toluene with benzyl alcohol, excellent catalytic activity with 96% conversion and a good recyclability over seven times in esterification of 1, 6-hexanedioic acid with 2-ethylhexanol.

Graphical abstractA mild and facile synthesis of fluorinated sulfonated polystyrene chloridized resin from CF3SO3H has been reported to enhance the stability and acid strength of parent resin.Figure optionsDownload full-size imageDownload as PowerPoint slide
