Investigation on Synthesis of Trimethylolpropane (TMP) Ester from Non-edible Oil

Bulletin of Chemical Reaction Engineering & Catalysis, 2020
Trimethylolpropane (TMP) ester is an eco-friendly lubricant that fully biodegradable and known as bio lubricant. In this study, TMP ester was produced from waste cooking oil and rubber seed oil through a two-step synthesis approach.

An acceleration of microwave-assisted transesterification of palm oil-based methyl ester into trimethylolpropane ester. [PDF]

Sci Rep, 2020
AbstractMicrowave-assisted synthesis is known to accelerate the transesterification process and address the issues associated with the conventional thermal process, such as the processing time and the energy input requirement. Herein, the effect of microwave irradiation on the transesterification of palm oil methyl ester (PME) with trimethylolpropane ...

Optimization for Epoxidation of Malaysian Jatropha curcas Oil Based Trimethylolpropane Ester Biolubricant [PDF]

Applied Science and Engineering Progress, 2021
Epoxidized Jatropha curcas-based trimethylolpropane triester (ETMPJO) was prepared by the in-situ epoxidation reaction of trimethylolpropane ester (TMPJO) catalyzed by hydrogen peroxide (H2O2) in the presence of formic acid. The epoxidation process was optimized through the variable parameters such as hydrogen peroxide to tmpjo molar ratio, formic acid

Wear prevention characteristics of a palm oil-based TMP (trimethylolpropane) ester as an engine lubricant [PDF]

Energy, 2013
This paper presents the experimental results carried out to evaluate wear prevention characteristics of a palm oil-based TMP (trimethylolpropane) ester using a four-ball machine for different regime of lubrication. The TMP ester is produced from palm oil, which is biodegradable and has high lubricity properties such as a higher flash point temperature ...

The effect of palm oil trimethylolpropane ester on extreme pressure lubrication

Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology, 2013
This paper presents the experimental results for the extreme pressure characteristics of a palm oil-based trimethylolpropane (TMP) ester blended with paraffin oil obtained using a four-ball machine. The load and speed of the sample were set between 20–120 kg and 1770 rpm, respectively.

Poly(ester amine) Synthesized from Trimethylolpropane Triacrylate and Spermine as an Efficient siRNA Carrier

Journal of Nanoscience and Nanotechnology, 2013
Small interfering RNA (siRNA) is a promising candidate for gene therapy due to the strong and specific gene silencing effects. However, to effectively silence any protein, lack of an efficient delivery system is major obstacle for siRNA therapeutics. In the present study, we report on the development of a novel poly(ester amine) (PEA) as an efficient ...

Lubricity of bio-based lubricant derived from different chemically modified fatty acid methyl ester

, 2022
In this research, polyol ester was used as the source of a biolubricant. The trimethylolpropane (TMP) and pentaerythritol ester (PE) were produced from palm oil methyl ester; they are biodegradable and have high lubricity properties.
