The kinetic studies of esterification of n- propionic acid and 2- propanol were carried out in a stirred and temperature controlled batch reactor. Sulphuric acid was chosen as a homogeneous catalyst in the present esterification reaction. The influence of different variables on rate of reaction such as reactant molar ratios, catalyst concentration and reaction temperature was studied. The molar ratio of acid to alcohol was varied from 0.5 to 1.5, the reaction temperature ranging between 50oC and 70oC and catalyst concentration was from 1.0 to 3.0 weight percent. Box- Behnkem design of experiments was employed in the present study, from which the batch kinetics were evaluated. The reaction rate in terms of acid concentration was found to be second order by employing integral method of analysis. Also, an equation was correlated using non linear regression analysis to predict the reaction rate constant.
