Abstract

The kinetics of esterifying lactic acid and its oligomers with ethanol over Amberlyst 15 cation-exchange resin have been determined via batch reaction studies. The kinetic model for esterification of lactic acid and its oligomers uses nth-order, reversible rate expressions for esterification and oligomerization reactions. Rate constants, activation energies, and equilibrium constants were generated via regression of experimental results. Model predictions for esterification of 20%, 50%, and 88% lactic acid solutions in water are in good agreement with experimental results over a wide range of experimental conditions.
