Title: Catalytic Synthesis of n-butyl Acetate with γ-Al_2O_3 Supported Nano-sized SO_4~(2-)/TiO_2 Solid Super Acid
Abstract: γ-Al2O3 supported nano-sized SO42-/TiO2 solid super acid was prepared and n-butyl acetate was synthesized withγ-Al2O3supported nano-sized SO42-/TiO2solid super acid as catalysts,with acetic acid and nbutanol as reactants.Effects of molar ratio of alcohol /acid,amount of catalyst,reaction time on the reaction were studied.Under optimum synthesis condition,the conversion rate of acetic acid was 97.6 %.As a result,after the catalyst was used repeatedly for 6 times(3 h one time),the 3 h conversion rate of acetic acid become down to 90.1 % for the esterificational reaction of acetic acid and n-butanol.The selectivity of catalyst was good and no outgrowth has been found by gas chromatography.
