Study of contamination of cotton oil with harmful chemicals

The monograph is devoted to consideration of scientific and technological aspects of improving the technology for obtaining refined press and extraction oils from low-grade and substandard cotton seeds using the method of preliminary clarification of crude (black) oils with the help of clay adsorbent modified by carbamide, reduction of harmful substances in their composition. The book studies the composition and features of the chemical properties of oils obtained from various cotton seeds. Features of the process of adsorption purification of vegetable oils. Characteristics of cotton seeds and products of their processing. Methods of research of raw materials and products of partial and final oil refining. Analysis of raw materials. Quality analysis of black oil. Refined oil quality analysis. Laboratory installation for adsorption purification (bleaching) of vegetable oils. Methods for analyzing natural clays and adsorbents derived from them. Mathematical processing of the obtained results of measurements and analyses. The process of cotton oil bleaching on various clay adsorbents has been studied. Influence of technological factors on the cotton oil purification degree is studied. The selectivity of the adsorbent process has been studied.
