Alkaline metal hydroxides (KOH and NaOH) are cheaper than metal alkoxides, but less active. They can give the high conversions of esters just by increasing their concentration from 1% to 2%. Various methods of transesterification of vegetable oil to develop bio lubricant are listed below. 5. Epoxidation
Transesterification of Vegetable Oils: a Review
Transesterification of Vegetable Oils In the transesterification of vegetable oils, a triglyceride reacts with an alcohol in the presence of a strong acid or base, producing a mixture of fatty acids alkyl esters and glycerol 25,26 (Scheme 4). The overall process is a sequence of three consecutive and reversible reactions, in which di-
sourced from fatty acids of vegetable oils may result in significant cost reduction of the synthesized lube oil [5]. In the study carried out by Ghazi et. al. [6], the kinetics of the transesterification synthesis of bio-lubricants from jatropha curcas oil was done at varying temperatures and constant pressure. Their findings showed that the
Aspects of Non-edible Vegetable Oil-Based Bio

What happens if I use vegetable oil instead of machine
Vegetable oil will gum up, attract dirt and dust, and eventually end up a huge mess. DO NOT use it. Mineral oil is a food-safe oil not normally used as a cooking lubricant, but it is the go-to for replenishing woods and lubricating mechanical parts of cooking utensils. It won't gum up, and is OK to use in a pinch. Most machine oils are a bit thin; they'll get into crevices like in door hinges

Transesterification Kinetics of Waste Vegetable Oil
The kinetic analysis method using the non-isothermal technique was proposed to determine the kinetic parameters for the transesterification reaction of waste vegetable oil (WVO) in supercritical alcohols. To investigate the transesterification of WVO, experiments have been carried out with WVO and alcohols at three molar ratios of 1:6, 1:12 and 1:18 for both supercritical ethanol (SCE) and

Non-Edible Plant Oils as New Sources for Biodiesel
Moreover, these oils could be more expensive to use as fuel. Hence, the contribution of non-edible oils such as jatropha and soapnut will be significant as a non-edible plant oil source for biodiesel production. Jatropha is grown in marginal and waste lands with no possibility of land use competing with food production.

Vegetable oil
Vegetable oils, or vegetable fats, are oils extracted from seeds, or less often, from other parts of fruits. Like animal fats, vegetable fats are mixtures of triglycerides. Soybean oil, rapeseed oil, and cocoa butter are examples of fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of fruits.
