BIOLUBRICANTS FROM NATURAL WASTE OILS AND FATS

The increase of ecological concern inspires research of raw materials from renewable sources in lubricant industry. Growing consumption of different lubricant types which are mostly mineral based or synthetic, leads to accidental but unavoidable inflow of considerable lubricants quantity into the environment. Therefore biodegradable lubricants produced from natural oils and fats become important if application is possible. Biodegradable lubricants produced by classical procedure from high quality natural oils and fats can be several times more expensive compared to conventional lubricants. Lower prices of waste natural oils and fats makes biodegradable lubricants much more competitive on the market. In this work the procedure of chemical synthesis, in which biodiesel (mixture of fatty acid methyl esters) is the raw material for TMP lubricants preparation will be presented as well.
