Abstract

This paper reports on the two-phase acid-catalyzed esterification of dilute acetic acid and 1-heptanol. It reveals larger turnover number of the Amberlyst 15 than sulfuric acid. It indicates that adsorbed water on protonated sites is replaced by acetic acid, then moving into the organic phase to promote the reaction.

Keywords
