THE PROCESSING OF INDUSTRIAL OILS FOR ALTERNATIVE BIOPRODUCTS LUBRICANTS : METHODS AND THEIR EFFECTIVENESS

The innovative way of increasing the efficiency of traditional methods for processing the optimized compositions of rape or soy-gm oils with the addition of ratsin oil (the so-called compols ) by the methods of glycolysis and esterolysis is considered. These compositions are processed into alternative biocomponents of the branch of lubricating materials, in particular into biooils. It has been shown that the earlier developed methods of glycolysis — esterolysis of compols is characterized by low indicators, in particular selectiveness in relation to biooils, their output and quality. It is suggested to realize these methods as consisting of two stages with their first common stage — alcoholysis of compols by glycerine (glycerolysis-2) and the following stage which involves glycolysis or esterolysis of the intermediate product of glycerolysis. Due to the application of such technique, a drastic increase of selectiveness methods is achieved. It is demonstrated that in their functional properties and tribological characteristics new biooils are on a par with the best traditional base oils, in particular such very expensive and ecologically dangerous ester-type synthetic oils.
