The article studies the possibility of extraction of monounsaturated oleic acid from highly stable vegetable oils produced at industrial scale. To solve the set tasks, have been selected samples of vegetable oils, present in the domestic market with a high content of unsaturated fatty acids: cottonseed and sunflower, imported rapeseed and olive oils. These oil samples were degraded by hydrolysis, recovered by acid treatment, and purified by repeated recrystallization in ethanol. The composition of saturated and unsaturated fatty acids included in triglycerides of vegetable oils was investigated using gas chromatography-mass spectrometry (GC-MS). In the obtained samples, the fatty acid composition and physical and chemical parameters were determined. Oleic acid technical grade obtained from sunflower oil contains 97.35 % fatty acids. The production of oleic acid technical grade will be primarily focused on the domestic market of Uzbekistan.
