摘要
The used perfluorosulfonic acid ion exchange membrane was treated to recycle the perfluorosulfonic acid resin. The perfluorosulfonic acid resin/silica composite catalysts were prepared by a sol gel method and characterized by FTIR, TG, BET measurements. The composite catalysts obtained were used in esterification of HAc and butyl alcohol. The results showed that at n (HAc)∶ n (butyl alcohol)= 1 3∶1 0 , 3 g catalyst, 110 ℃ and 2 h, butyl acetate could be obtained in yield of 92 4%.
