The table of contents entry. Using methyl oleate, a common fatty chain in most vegetable oils, an advanced lubricating additive can be synthesised. The additive is metal and sulfur free and is a highly effective additive when used in biobased lubrication fluids. An advanced metal and sulfur free lubricating additive was synthesized from methyl oleate.
