<p>Organic material, such as lubricating oil, may be protected from degradation due to the effects of oxygen by the addition of the reaction product of 4,4 min -methylenebis-(2,6-di-tert-butyl phenol) and a tri-sec- C4-12 alkyl orthoborate. The invention includes the new ester products of such a reaction, i.e. 4,4 min -methylenebis-(2,6-di-tert-butyl phenol) mono- or di-(di-sec-C4-12 alkyl orthoborate) ester, and their preparation by such a reaction.</p> |
