Abstract: (4-phenylthio)phenyl diphenyl sulfonium hexafluorophosphate were prepared by the condensation of biphenyl sulfoxide with biphenyl sulfide,in the presence of P2O5 used as dehydration(agent) and methanesulfonic acid used as solvent.4-(phenylthio)triphenylsulfonium hexafluorophosphate was identified by elemental analysis,UV,IR,G-MC and H-NMR.The sulfonium salt has better curing character to epoxy resin.

Key words: sulfonium salt, biphenyl sulfide, methanesulfonic acid
