Preparation of Fructone Catalyzed by a New Solid Acid SO_4~(2-)MoO_3-TiO_2

LIAO De zhong (Department of Chemical Engineering,Yueyang Normal College,Yueyang,414000 China)  
A new solid acid catalyst SO 2 4MoO 3-TiO 2 was prepared.By characterization of Fourier-Transfer IR spectrum,the surface of the catalyst had centers of strong acid.And it had high catalytic activity in preparation of fructone.The optimum condition was obtained as follows:acetoacetic ethyl ester 0.3mol,glycol 0.6mol,cyclohexane 30ml,the catalyst 3g,reaction temperature 110℃,reaction time 1.5h.Under this condition,the yield of fructone was 90%.And the catalyst can be recovered easily and used repeatedly for many times
