Immobilized lipase-catalyzed esterification for synthesis of trimethylolpropane triester as a biolubricant

Renewable Energy, 2019
Abstract Synthetic oleochemical esters of polyols and fatty acids are biodegradable and possess desirable technical and ecological properties. Trimethylolpropane (TMP) triester has been widely applied as a hydraulic fluid. TMP triester was effectively synthesized by lipase-catalyzed esterification from TMP and high oleic fatty acid from palm oil ...

Synthesis of Biophenol‐Derived Biolubricants With Enhanced Antioxidant Properties

Journal of the American Oil Chemists' Society
ABSTRACTThe main challenge to the use of vegetable oils as green lubricants is their oxidative stability. In this work, biolubricants with efficient antioxidant properties have been specifically designed and synthesized with the aim of maximizing the oxidative stability of vegetable oils by combining biophenols (p‐coumaric, ferulic, and sinapic acids ...

Synthesis and characterization of biolubricants by ethyl epoxidation of corn oil

V Seven International Multidisciplinary Congress
Lubricating oils are derived from petroleum and are widely used in the industrial sector, with the aim of reducing wear caused by friction on metal parts. Currently, mineral lubricants are commercially the most used throughout the world, they are a complex mixture of paraffinic, olefinic, naphthenic and aromatic hydrocarbons with 20 to 50 carbon atoms.

Clean synthesis of biolubricants for low temperature applications using heterogeneous catalysts

Journal of Molecular Catalysis B: Enzymatic, 2011
Abstract 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.

Synthesis of Biolubricant Trimethylolpropane Trioleate and Its Lubricant Base Oil Properties

Energy & Fuels, 2017
Trimethylolpropane trioleate (TMPTO) could significantly reduce environmental pollution compared to mineral oils. In this study, oleic acid (OA) and trimethylolpropane (TMP) were used to synthesize TMPTO, and the synthesis process was optimized by single-factor experiments to obtain the highest yield.
