Abstract

Ultraviolet and mass-spectrometric methods have been developed for the analysis of typical and nonproprietary oxidation inhibitors. These inhibitors are phenothiazine, N-phenyl-alpha-naphthylamine, N-phenyl- beta-naphthylamine, and p,p’-dioctyidiphenylamine. The methods are applicable without prior separation of the additives and are valid for concentration ranges of 0.05 or less to 2.4 wt.% of each inhibitor.
