Nevmyvaka D. Improvement the technology of surface-active derivatives of fats using transesterification

The object of study - the technology of surfactants derived of fats. The a purpose of the study - scientific and practical foundation and improvement of technologies for the production of surface-active derivatives of fats using transesterification as a promising way for obtaining high-quality emulsifiers. Research methods and instruments: the fatty acid composition of the products and component composition defined by GLC (gas chromatograph Hewlett Packard HP-6890) and thinlayer chromatography and titrimetry techniques; experimental data processing carried out with using of software packages Microsoft Excel, MathCAD. Theoretical and practical results: the technology of monoacylglycerols, lactic mono-, diacylglycerols, polyglycerol esters of fatty acids has been proposed. Surface-active properties for obtaining products have been evaluated. Scientific novelty lies in the fact that the first - the experimentally identified quantify degree of conversion of the ethyl esters of fatty acids to monoacylglycerols depending temperature, reaction time and mixing intensity of the glycerolysis; - proved possible to obtain the lactic mono-, diacylglycerols by esterifying glycerol with lactic acid and following transesterification of obtaining esters with fat; - experimentally demonstrated the possibility of obtaining polyglycerols esters of fatty acids by reacting sodium glycerate with triglyceride; - the basic surfactant properties of substances which was produce by the new technologies. Degree of implementation: derived surfactants tested in experimental-industrial conditions at the Kharkiv biscuit factory, PPTC "UCI" (Kharkiv), results of the thesis introduced in the educational process of the department of technology of fats and fermentation products NTU "KPI". Application - for obtaining surface-active substances in the oil and fat industry.
