A Review of Bio-lubricant Production from Vegetable Oils Using Esterification Transesterification Process

Since long time ago, petroleum oil has been used as a lubricant in motor vehicles. But, the uses of lubricants petroleum can pollute the environment and disrupt marine ecosystems and terrestrial. On the other hand, the use of lubricants in the world in 2008 reached 46 million kiloliters/year and increased by 2% every year. The future prospect the uses of lubricant petroleum on the vehicle’s engine is predicted to have a bad prospect. Thus began research to identify suitable materials to replace petroleum based lubricants. It can produce from vegetable oils and animals oils by chemical modification. But, bio-lubricant properties are easily damaged so we need more research to improve the shelf life of the bio-lubricant. The research must be done to improve the characteristics by adding a bio-lubricant additive
