Physicochemical and corrosion properties of polyol ester-commercial motorbike oil blends

Cogent Engineering
Modern industry has increased gasoline use, emphasizing the need for engine oil to reduce friction, wear, and heat. Anti-corrosion-based lubricants, especially esters derived from bio-based oils, are of interest because they reduce toxicity and increase ...

Synthesis and Characterization of Trimethylolpropane Based Esters as Green Biolubricant Basestock

Biointerface Research in Applied Chemistry, 2021
Bio-based lubricant is crucial to be developed considering the toxicity risk, climate change, energy security, and green-environmental approach. In this work, trioleate trimethylolpropane (TOTMP) (1) was synthesized through the esterification between trimethylolpropane (TMP) and oleic acid (OA) using a sulfuric acid catalyst.

Biotechnological esterification of oleic acid with 2-ethylhexanol in biolubricant synthesis technologies

Žemės ūkio mokslai, 2017
The possibilities of waste materials re-use in biosynthesis of grease were investigated. In this paper, 2-ethylhexanololeate synthesis from 2-ethylhexanol and oleic acid using industrial enzymes is discussed. In order to select an effective enzyme for the mentioned synthesis, the selection of industrial lipases was carried out.
