Papchenko V. Technology of mono-, diacylglycerines and diethanolamides of fatty acids by amidation of sunflower oil

The object of research: sunflower oil acylglycerols amidation. Aim: scientific rationale and practical development of new technology of mono-, diacylglycerols and diethanolamides of fatty acids by diethanolamine amidation of acylglycerols of sunflower oil. Methods: chromatographic, titrimetric, infrared spectroscopy; differential analysis method; additive-group method; stalagnometer method; electrochemical method of polarization resistance; the method of Ross-Miles; standard methods; mathematical methods using the software packages Microsoft Excel, Mathcad, Mathlab. Theoretical and practical results: Developed technology and technological scheme of diethanolamine amidation of sunflower oil and obtaining of concentrate of mono-, and diacylglycerols and composite surfactants based dietaholamides of fatty acids. Created kinetic and statistical models. Estimation of surface-active properties of the obtained products. Scientific novelty: the first time proved that by reaction of amidation of sunflower oil by diethanolamine formed mono-, diacylglycerols parallel with diethanolamides of fatty acids. Revealed that the reaction between triacylglycerols of sunflower oil dy diethanolamine proceeds by stages with the formation of hydrogen bonds between the components of the reaction mixture and proposed mechanism amidation. Obtained new scientific data on the kinetics of amidation of triacylglycerols of sunflower oil and tripalmitin by diethanolamine. A kinetic model of amidation have been created. The technological conditions for maximum output products and mathematical models. Concentrates of mono-, diacylglycrines and composite surfactants have been obtained. Defined surface and interphase tension, the work of adsorption, emulsifying, blowing, adsorption properties of their solutions and antispraing and stabilizing ability. Degree of implementation: results of the thesis are used in the learning process of Technology Fats and fermentation products Department of NTU "KPI" in the preparation of specialists in the field of "Food Technology and Engineering" 7.091705 specialty "Technology of fats and fat substitutes". Testing concentrated mono-, diacylglycerines in margarine stock in test laboratories UkrNDIOZh NAAS (Kharkiv) composite surfactants in cosmetic cream in stock Ltd "Aromat" (Kharkiv); adsorption-active substances based on amidated by diethanolamine oil and fat raw material with production corrosion inhibitors in LLC "PROTEH" (Kyiv),on which developed TU 26.6-38799429-001-2005. Field of use - oil and fat, food, cosmetics and technical industries.
