Clean synthesis of biolubricants for low temperature applications using heterogeneous catalysts
CO Åkerman, Y Gaber, N Abd Ghani, M Lämsä… - Journal of Molecular …, 2011 - Elsevier
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 esters from trimethylolpropane (TMP) and carboxylic acids from C5
to C18 has been studied and compared using different heterogeneous catalysts (silica–
sulphuric acid, Amberlyst-15, and immobilised lipase B from Candida antarctica). Silica …
