Evaluation of the lubricating power of chemical modified Sesame oil additivated with Cu and Al2O3 nanoparticles

open access: yesDyna, 2018
Biolubricant from modified sesame oil (Sesamumindicum L.) was produced. The lubricant base consists of a mixture in a volume ratio of 74 parts of epoxidized sesame and 26 parts of transesterified sesame oil.

Ultrasonic Intensification To Produce Diester Biolubricants

open access: yesIndustrial & Engineering Chemistry Research, 2019
Biolubricants synthesized from vegetable oils with oleic acid and 1,3-propanediol possess better cold flow properties and have a smaller environmental footprint than mineral-based lubricants. However, their synthesis is lengthy (>6 h) and requires temperatures above 120 °C.

Alkali‐Catalyzed Synthesis of Acylglycerol Estolides Exclusively from Castor Oil

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
This work advances sustainable chemistry by converting renewable castor oil into high‐performance estolides via solvent‐free, low‐energy catalysis. ABSTRACT Estolides are oligomers composed of fatty acid (FA) monomers linked through secondary ester bonds located along the mid‐chain region.

Valorisation non alimentaire des huiles de friture usagées en tant que lubrifiants biodégradables

open access: yesOléagineux, Corps gras, Lipides, 2005
The market of used frying oils (UFO’s) collection in Europe is estimated to about 350,000 tons a year. Since the dioxin crisis in 1999, the main recycling ways of this raw material, considered as a waste, concern the oleochemical applications namely the ...

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 4, Page 1821-1834, July/August 2026.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...
