Filinska T. Technology processing of secondary fatty raw materials in the multipurpose products

Object of study: processes of methanolysis, ethanolysis and glycerolysis of fat. The aim of the thesis is to develop science-based technology for the processing of secondary fatty raw materials by alcoholysis using heterogeneous sulfonated polymeric catalysts. Methods: IR-spectroscopy, mass-spectrometry, thermogravimetric analysis, thin layer chromatography, determination of acid, iodine number, moisture content and density performed by standard methods. Theoretical and practical results: developed technology of chicken fat and waste palm oil, which is based on the use of the method alcoholysis using new heterogeneous sulfonated polymeric catalysts. Scientific novelty: first scientifically substantiated and experimentally validated the application of new heterogeneous at the alcoholysis of fatty raw materials, finded a temperature operating range of catalysts and set rational technological conditions of their use in processes of methanolysis and glycerolysis. Degree of implementation: developed technology tested in enterprises "Plant UKRBUDMASH" (Poltava) and "Zaporozhye Biofuel Plant" (Zaporizhzhya). Glycerolysis products of waste palm oil were tested in conditions of "Creative Group" (Kirovograd). Application: for food and chemical industry in the production of fatty acid esters and partial acylglycerols, which are used as biofuel, plasticizers, surfactants, etc.
