heal.abstract	The environmental issues associated with the use of petroleum products and the geopolitical strategies concerning crude oil manipulation are the driving forces behind the introduction of biobased lubricants (biolubricants) from renewable raw materials. Oleochemical esters constitute a class of products that improve the thermal and cold-flow instability of the neat vegetable oils and fulfill the basic requirements as lubricant basestocks for environmentally sensitive and special applications. Among the esters used in biolubricants manufacturing are the polyol esters deriving from neopentylalchohols. Based on this background crude pomace oil was utilized as feedstock for the production of environmentally adaptable lubricant basestock. The crude pomace oil is obtained from the olive pomace that remains from the cold pressing of the olives and it is either further processed for nutrition purposes or used as such in the industry sector. The advantages of crude pomace oil lie in its low cost and in the high levels of monounsaturated fatty acids it contains. Crude pomace oil was obtained from local (Greek) pomace oil plant and after dehydration it was refined using alkaline neutralization process. A two stages transesterification reaction was followed for the production of biobased lubricants. The refined oil was converted to fatty acid methyl esters using excess of methanol and sodium methoxide as catalyst. The resulting methylesters were subsequently transesterified with TMP (Trimethylolpropane) in the presence of an alkaline catalyst in order to produce the desired oleochemical ester. The synthesized esters were evaluated as potential lubricant basestock regarding their physicochemical properties such as viscosity index, pour point and acid value. The lubricating performance of the pomace based biolubricants was examined by assessing the antiwear and friction properties.	en
