Title
Acidolysis of tripalmitin with capric acid using Nb2O5 and MgO as heterogeneous catalysis
Abstract

The present work reports the synthesis of structured lipids by acidolysis of tripalmitin (PPP) and capric acid (C) with heterogeneous catalysts. The inorganic oxides Nb2O5 and MgO were selected as catalysts for their acid and base properties, respectively.The solids were characterized by XRD, N2 adsorption isotherm, atomic absorption spectroscopy and SEM.The conversion of PPP at 20 h and 180 °C was 62% for MgO and 18% for Nb2O5. As regards the yield of PPC + PCP, the maximum value for MgO was 40% and 14% for Nb2O5. The yield of the structured lipid PCC + CPC was 14% and 2% for the base and acid solid, respectively.
