Researches on hydrogenation of sec-butyl acetate to sec-butyl alcohol

Using alumina as the support,a series of CuO/Al2O3 catalysts was prepared by impregnation method.The influence of reaction conditions of sec-butyl acetate hydrogenation was investigated.The results showed that the conversion of sec-butyl acetate and the selectivity to sec-butyl alcohol,butyl alcohol and alcohol were 98.16%,20.48%,93.37% and 88.81% respectively under the optimum reaction condition as follows:reaction temperature 265 ℃,reaction pressure 8.0 MPa,space velocity 0.2 h-1 and n(hydrogen)∶ n(sec-butyl acetate) =20.
