A mathematical kinetics model has been developed for the reaction of stearic acid with isopropenyl acetate to form isopropenyl stearate. Though the reaction is reversible, the kinetics can be described mathematically most simply by a pseudo first order irreversible reaction model. The model predicts the rate of formation of isopropenyl stearate as a function of time, temperature, catalyst concentration and equilibrium concentration of isopropenyl stearate. Equilibrium is determined from an empirical equation as a function of the ratio of the original concentration of the reactants. Temperature has little effect on the equilibrium.
