Clean synthesis of biolubricants for low temperature applications using heterogeneous catalysts
Biolubricants derived from vegetable oils are environmentally compatible products due to their low toxicity and good biodegradability. Synthetic esters based on polyols and fatty acids possess suitable properties for lubricant applications, even at extreme temperatures. In this work, synthesis of es...

Biolubricants derived from vegetable oils are environmentally compatible products due to their low toxicity and good biodegradability.
