Synthesis of furfuryl acetate by solid super acid catalyst SO_4~(2-)- ZrO_2

Furfuryl acetate was synthesized with solid super acid catalyst SO 2- 4 ZrO 2.The optimum preparation condition for the catalyst was that the sediment obtained by adding ammonia water into solution of ZrOCl 2·8H 2O was dried and impregnated with 0.75 mol/l H 2SO 4,then calcined 4 h at 600 ℃.The optimum reaction condition for furfuryl acetate was that the mixture of 0.25 mol acetic acid,0.25 mol furfulyl alcohol,80 ml toluene and 4 g catalyst at room temperature,reacted for 2 h then refluxed until no water came into being.The yield of furfuryl acetate was 90%.The catalyst could be used 6 times without regeneration.
