| Abstract: | Some kinds of solid acids of SO 4 2- /Fe 2O 3 ZrO 2 SiO 2,SO 2- 4/Fe 2O 3 SiO 2,SO 2- 4/ZrO 2 SiO 2,SO 4 2- /TiO 2 SiO 2 were prepared and used to catalyze the gas phase esterification of acetic acid and butanol It was found that this kind of solid acid had good catalytic properties:the yield and selectivity of butylacetate were found to be 86 33% and 93 15% respectively It may be a new type of environmental friendly catalyst for gas phase esterification In above reaction,the GHSV of HAc and butanol and reaction temperature have great effects on reaction in comparison with the effects of the granular size of catalyst From the XRD patterns of SO 4 2- /Fe 2O 3 ZrO 2 SiO 2,it can be seen that the components of catalyst exist mainly in amorphous state |
