A series of S2O8 (2-)/x wt% Ce-Al-Fe-O solid acid catalysts were prepared by the sol-gel method. Their catalytic performances for the synthesis of n-butyl acetate from acetic acid and n-butanol were investigated. The catalytic properties and crystalline phases of S2O8 (2-)/x wt% Ce-Al-Fe-O solid acid catalysts were characterized by XRD, IR, TG/DSC and SEM techniques. Experimental results showed that S2O8 (2-)/10 wt% Ce-Al-Fe-O solid acid catalyst exhibited the highest catalytic activity with 99.90 % esterification efficiency of acetic acid. Moreover, the S2O8 (2-)/10 wt% Ce-Al-Fe-O solid acid catalyst showed excellent stability with no obvious change in catalytic activity even after being used repeatedly for eight times.
