With the purpose of decreasing the content of the related substances in plant oils, subjected to hydrogenation, the technology stipulates their refining. Alkaline reagent is primarily used for implementing this process. However, some substances, related to the oil and the solvent (if it is used) don’t react with alkali and form new complex compounds which pass into the oil content. This permits hydrogenation. Though their amount, at first glance, is not great, they decrease the activity and stability of the hydrogenising catalysts. We studied the possibility of applying synthetic NaX and CaX type zeolites with different binders for selective purification of the refined miscella and cottonseed oil. For the quantitative evaluation of refining the miscella by zeolits, we used the spectral method of area comparison. The presented results show that the maximum effect lighted by gossypol, karotinoid and their derivatives reach to the synthetic zeolits NaX (kaolinite as a binder). So, this process can be applied in both refining and hydrogenation production
