Esterification of Acetic Acid with n-Butanol Using Heteropoly Acid Supported Modified Clay Catalyst

摘要

Esterification of acetic acid with n-butanol catalyzed by supported heteropoly acid dodecatungsto-phosphoric acid, H3PW_(12)O_(40) (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.
