Description
Trimethylolpropane (TMP) esters are biodegradable synthetic lubricants that can be used as a base oil alternative to mineral oils, polyalphaolefins, and diesters. They are produced by combining fatty acid methyl esters (FAMEs) and TMP through chemical or enzymatic catalyzed synthesis methods. TMP esters have good stability and low-temperature performance, making them suitable for use as a lubricant base oil. They can also be produced from waste cooking oil and rubber seed oil.
Here are some ways TMP esters have been used in lubricants:
- Tribological performance
In one study, TMP ester was used as a base lubricant, graphene oxide (GO) as a nanoparticle additive, and oleic acid (OA) as a surfactant. Tribological testing showed that the TMP + GO + OA combination had increased dispersion stability compared to TMP + GO alone. The presence of OA also reduced the coefficient of friction of the samples.
- Wear prevention
A four-ball wear test was used to investigate the effect of palm oil-based TMP ester under wear preventive test (hydrodynamic test). The HFRR (High frequency reciprocating rig) configuration was also used to investigate the effect of palm oil-based TMP ester under fluid film lubrication
