Preparation of Novel High-Temperature Polyol Esters from Vegetable Oils

الملخص EN

The aim of this work was to synthesize a high-temperature polyol ester from Jatropha oil.

The synthesis process was accomplished via chemical modifications involving epoxidation to remove the double bonds in Jatropha oil, hydrolysis to add hydroxyl groups, and then esterification with pentaerythritol to form the saturated polyol ester.

The high decomposition temperature 359°C of the polyol ester was determined by thermogravimetric analysis.

The lower peroxide value 0.07 meq/kg and iodine value 0.02 mg I2/100 g of the polyol esters were also determined.
