Uzbekistan is taking comprehensive measures to develop the vegetable oil production industry. Unrefined cottonseed oil contains coloring pigments of various composition and properties. The purpose of this work is to develop a technology for obtaining effective adsorbents for the adsorption purification of cottonseed oil from natural kaolin Sultan-Uvays and to study the change in mineralogical properties. Natural kaolin in its natural form has low adsorption properties; methods of its activation and modification have been applied. In order to effectively adsorptive purification of cottonseed oil, natural kaolin Sultan-Uvays is activated and modified by various methods, mineralogical properties are studied by infrared spectroscopy, X-ray diffraction analysis, and the specific gravity of the obtained kaolin samples is determined.
