Synthesis and physical characterization of oleyl oleate using acidic heterogeneous catalyst sodium hydrogen sulfate NaHSO4

Abstract

The esterification of oleic acid with oleyl alcohol under mild conditions and without any additional organic solvent was studied. High yield (90%) is obtained at optimized conditions 8 h, 130 °C and catalytic amount NaHSO4 (10%). Analysis of the product of the reaction using FTIR, 1H and 13C-NMR showed the presence of oleyl oleate.
