Esterification of Acetic Acid with n-Butanol Using Heteropoly Acid Supported Modified Clay Catalyst
Esterification of acetic acid with n-butanol catalyzed by supported heteropoly acid dodecatungstophosphoric acid, H3PW12O40 (DTP), on acid modified Montmorillonite clay (AT-Mont) matrix were carried out. Among different catalysts, 20% DTP supported onto AT-Mont (15 min) showed the highest catalytic activity with 88% conversion having nearly 100% selectivity towards n-butyl acetate.
