文摘

A procedure to predict equilibrium conversion rate in two-phase media is proposed. It is applied to enzymatic esterification of oleic acid by 1-butanol. UNIFAC group contribution model is used to predict compounds activity coefficients. Modeling is compared to experiments for various conditions. Equilibrium conversion is found to be governed by initial 1-butanol activity.
