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.
