Environmentally Friendly Lubricants: The Role of Biopolymers in Modern Tribology

SPE Polymers, Volume 7, Issue 3, July 2026.
Biomass‐derived biopolymers modified for green tribology applications with reduced friction, wear, and environmental footprint. ABSTRACT Energy losses due to friction and wear are a major challenge for the energy efficiency and sustainability of mechanical systems, motivating the development of green tribology strategies.

Synthesis of trimethylolpropane trioleate by using stannous oxalate catalyst

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 3, Page 1587-1595, May/June 2026.
Abstract This study was conducted to synthesize trimethylolpropane trioleate (TMPTO) using a stannous oxalate catalyst and investigate the dependence of the esterification rate on reaction variables. The highest esterification rate of approximately 99% was achieved at a 2.75:1 oleic acid/trimethylolpropane, 1.5% catalyst amount, 180°C reaction ...

Wear Tests of a Potential Biolubricant for Orthopedic Biopolymers [PDF]

Lubricants, 2015
Most wear testing of orthopedic implant materials is undertaken with dilute bovine serum used as the lubricant. However, dilute bovine serum is different to the synovial fluid in which natural and artificial joints must operate. As part of a search for a lubricant which more closely resembles synovial fluid, a lubricant based on a mixture of sodium ...

Synthesis, reactivity and application studies for different biolubricants [PDF]

Chemistry Central Journal, 2014
Les huiles végétales ont des propriétés uniques différentes en raison de leur structure chimique unique. Les huiles végétales ont une plus grande capacité à lubrifier et ont des indices de viscosité plus élevés. Par conséquent, ils sont examinés de plus près en tant qu'huile de base pour les biolubrifiants et les fluides fonctionnels.
