Synthesis of Ethyl Acetate by Solid Superacid TiO_2/SO_4~(2-)

Ethyl acelate was prepared by esterification of alcohol and acetic acid using solid superacid TiO2/SO42- catalyst,and XRD and SEM was used to characterized the catalyst.The result indicated: the optional calcination time,calcination temperature and impregnated concentration of TiO2/SO42- are respectively 3h,500℃ and 1.5 mol / L;the optional reaction time,reaction temperature,dosage of catalyst and the ratio of alcohol to acid are respectively 15 min,100-105 ℃,2% and 1 1.3;the repetition usage make the catalyst became the safety,green,environment amity of catalyst.
