Temperature Dependence on The Synthesis of Jatropha Biolubricant [PDF]

IOP Conference Series: Materials Science and Engineering, 2011
Jatropha oil has good potential as the renewable energy as well as lubricant feedstock. The synthesis of jatropha biolubricant was performed by transesterification of jatropha methyl ester (JME) with trimethyl-ol-propane (TMP) with sodium methoxide (NaOCH3) catalyst.

Synthesis of Epoxide and Polyol Compounds as Intermediates for Biolubricant from Soybean Oil [PDF]

International Journal on Advanced Science, Engineering and Information Technology, 2020
Biolubricant derived from vegetable oils is one of alternatives to substitute petroleum based lubricant. The biolubricant is environmental friendly, biodegradable, non toxic and renewable since it is derived from the vegetable oils. Soybean oil is potential as raw material for synthesis epoxide compound as intermediate substances for biolubricant since
