PARTICIPATION OF REVERSED MICELLES IN THE INHIBITION OF HIGH-TEMPERATURE OXIDATION OF PENTAERYTHRITOL ESTERS

By electrophysical methods it has been shown that potassium-containing compounds, which, mixed with aromatic amines, exhibit synergism in th e inhibition of high-temperature oxidation of esters, form reversed mi celles when dissolved in pentaerythritol esters. The critical concentr ation of micelle formation is in good agreement with the content of po tassium salt that is most effective in high-temperature oxidation. A s cheme of the participation of reversed micelles in the inhibition of h igh-temperature oxidation of lubricants is proposed. (C) 1998 Elsevier Science Ltd. All rights reserved.
