THE QUANTITATIVE ANALYSIS OF N-PHENYL-ALPHA-NAPHTHYLAMINE AND 5-ETHYL-10, 10-DIPHENYLPHENAZASILINE IN ALIPHATIC TRIESTER BASE STOCK FLUID

摘要

A quantitative ultra-violet method has been developed for determining the quantity of two antioxidant additives (n-phenyl-alpha-naphthylamine and 5-ethyl-10,l0-diphenylphenazasiline) when blended with an aliphatic triester base stock fluid. The method has been applied to engine tested samples.
