| Abstract: | This paper studied the esterification of acetic acid with isopentyl alchol, using modified HBeta zeolite as catalyst. Reaction parameters were discussed. The acidity of catalyst was also characterized. The results show that the conversion of acetic acid can be up to 98% under the reaction conditions of catalyst 3 g, temperature 117～132 ℃, and time 2 h. When the catalyst was used repeatedly at least 8 times, its catalytic activity was not changed basically. |
