Synthesis of polyol esters by p-toluenesulfonic acid catalyst as synthetic lubricant oils

A most effective and less energy demanding method of producing fatty esters, polyol esters, by esterifying fatty acids, with a pentaerythritol and trimethylolpropan alcohols in the presence of an acid catalyst at elevated temperature wherein an azeotroping agent, particularly toluene, is used to facilitate continuous removal of water by distillation, formed as a by-product during the esterification reaction. The esterification reaction is completed within 5 hours, pentaerythritol and trimethylolpropan esters were produced.
