Abstract

Kinetic data in the esterification of lactic acid with ethanol have been obtained using Preyssler acid as a catalyst. The effects of different parameters such as the alcohol:acid molar ratio, reaction temperature and catalyst concentration have been examined. The activation energy, forward and backward rate constants and equilibrium constants were calculated in the temperature of 343–358 K.
