Kasianenko L. Technology for vegetable oil based lubricants production

The object of research is the technology of obtaining lubricating oils from oils. The subject of research is the technological parameters of hydrochlorination, epoxidation, triacylglycerols, fatty acid esters and their subsequent conversion into hydroxyl and ester compounds of oils, tribological and physicochemical properties of lubricating oils based on vegetable raw materials. The dissertation work is devoted to the development of methods for obtaining lubricants from oils by hydrochlorination or epoxidation with the subsequent production of oxygen - containing derivatives and the increase of the carbon radical. Several routes for the synthesis of chlorinated triacylglycerols (TAG) of sunflower oil have been developed, in particular hydrochlorination with dry HCl or chlorinated lime Ca(OCl)2.The interaction of chlorine-containing TAGs with sodium soaps of hydrofat (mainly acids of the C18 series), coconut oil (mainly acids of the C12,14series) and acetic acid was studied. Methods for obtaining epoxy compounds have also been developed, namely the method of UV irradiation of sunflower oil in a thin layer and the method of epoxidation with peracids. The interaction of epoxy groups with stearic, lauric and acetic acids to obtain a lubricant has been studied. It was found that the obtained compounds have high tribological characteristics and meet the criteria of bio-oils.
