In recent years, market requirements for oil color have increased, and light oils are in great demand [2, 3]. This means that the color requirements for “dark” additives (which have always been phenolates) automatically increase. Therefore, the discrepancy between the color index and the modern requirements for newly created additives is not a rare phenomenon. In this regard, it was decided to assess not only the efficiency of purification and colloidal stability, but also the color of the developed phenolyte additives of various alkalinity, in comparison with foreign analogues - the additive Oloa-219 (Chevron Oronite, USA) and the additive WFY007-1, produced by WanFY Chemical (China) [4].
