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

, 2016
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.
