Characterization of esters of fatty acids and dicarboxylic acids with Guerbet alcohols

  • Published:
Journal of the American Oil Chemists' Society

Abstract

Esters of some common fatty acids and diacids with Guerbet alcohols were prepared by p-toluenesulfonic acid-catalyzed esterification. Such materials are of interest in applications such as additives in various industrial products. Gas chromatography-mass spectrometry with chemical ionization using methane as ionization gas is an efficient characterization method for these Guerbet esters and diesters. Under these conditions, structural features such as molecular weight and site of branching are easily determined. The spectra of the present compounds were compared to those of di-Guerbet esters reported earlier and differences noted. The compounds were also characterized by 13C nuclear magnetic resonance spectroscopy.
