Title: Preparation of CeO_2-Ga_2O_3/Silica Gel and Its Catalytic Performance for Esterification Reaction
Abstract: A novel cerium modified catalyst made from Ga2O3 supported on silica gel was prepared and characterized by IR technique.Isobutyl propionate was synthesized from propionic acid and isobutyl alcohol with CeO2-Ga2O3/silica gel as the catalyst.The suitable conditions for preparation of the catalyst were: CeO2∶Ga2O3∶silica gel =2.7∶20∶77.3(mass ratio),and calcinating at 500 ℃ for 2.0 h.The optimized conditions of synthesizing isobutyl propionate were: propionic acid 0.20 mol,mole ratio of alcohol to acid 1.4,catalyst dosage 1.0 g,and reaction time 90min.The esterification rate could reach 98.4%.
