Catalytic synthesis of ethyl acetate by SO_4~(2-)/TiO_2-Al_2O_3-Al structured solid acid catalyst

The structured Al2O3-Al carrier was prepared by anodic oxidation of high-purity aluminum foils,and electrodeposition technology was used to deposit TiO2 into the nanoporous of anodic alumina.SO42-/TiO2-Al2O3-All solid acid catalyst was prepared by impregnation method,and was used as catalyst to synthesize ethyl acetate from acetic acid and ethanol.The results showed that the optional preparation and reaction conditions were as follows: calcination temperature 450℃,calcination time 2h,molar ratio of ethanol and acetic acid 1∶1,reaction time 2h,catalyst amount was 2.0g.
