Figure 7.14 Composition and temperature profiles for the BuAc system.

nonmonotonic temperature profile is observed as a result of a large boiling point temperature difference (^20 °C) between these two reactants. Figure 7.10 shows a different characteristic in the stripping section where the compositions are distributed along the HAc/AmAc edge.

Before leaving this section, it should be pointed out that the type III flowsheet is probably the most general configuration for acetic acid esterification. In addition to BuAc and AmAc systems, the production of n-propyl acetate, isobutyl acetate, isoamyl acetate, and n-hexyl acetate also fall into this category when economic factors are taken into consideration.
