Abstract

Synthesis experiments of isopropyl palmitate, an emollient ester, were conducted using various reactant molar ratios and enzyme concentrations. Reactions were catalyzed by Candida rugosa or Penicillium camemberti lipases immobilized on magnetic poly(styrene-co-divinylbenzene). A kinetic model for the esterification reaction was developed based on a ping-pong bi-bi mechanism and validated with the experimental data obtained herein. Systems with different catalysts were compared, and correlations were found between parameters. Satisfactory predictions were obtained through curve fitting (R-2 of 0.89 for C. rugosa and R-2 of 0.92 for P. camemberti). (AU)
