| Abstract: | The sulfonated poly aryl ether ketone ketone(S PEKK) with various sulfonation degree was prepared by reaction of PEKK with sulfuric acid as sulfonating agent and solvent.The effect of concentration of sulfonic acid and reaction temperature on sulfonating degree ware investigated.S PEKK was characterized by IR,DSC and X ray diffraction,and that S PEKK used as catalyst for the syntheses of ethyl acetate and n butyl acetate was investigated.The results show that S PEKK exhibited good catalytic activity and could be used repeatedly. |
