A new class of oleochemical based polyol esters of general formula 1 are prepared by esterification of different polyols having 5-6 carbon atoms and 2-4 hydroxyl groups with 10-undecenoic acid or/and undecanoic acid with a hydroxyl value of ≦1.0 mg KOH/g. Wherein R

The properties indicate their potential as promising lubricant base stocks for automotive lubricants, metal working oil, hydraulic oil and other industrial applications. Vegetable oils provide most of the desirable lubricant properties such as good boundary lubrication, high viscosity index, high flash point and low volatility. Synthetic esters prepared from renewable resources like vegetable oils exhibit better performance at a lower cost compared to mineral oil based synthetic esters.
