Preparation and Catalytic Activity of Ce(SO4)2·xH2O-CuSO4·yH2O Composite Catalysts for Synthesis of Carboxylic Esters
Abstract:
Ce(SO4)2·xH2O was prepared by hot impregnation method from CeO2 and hot concentrated H2SO4 and mixed with CuSO4·yH2O to give composite catalysts.In syntheses of isopenty l acetate and dibutyl phthalate at optimum conditions the composite cataly sts gave conversion of the corresponding carboxy lic acids 63.2% and 68.8%, respectively. The cataly tic activity of the composite catalysts has been discussed in terms of the orbit structure of the sufficient energy-level of rare earth and transition metal ions and Brönsteds acid-base theory.
