摘要

Three convenient chromatographic methods were developed for the quantitative analysis of N-phenyl-beta-naphthylamine in samples of N-phenyl-alpha-naphthylamine. The TLC method makes use of dipropylene glycol impregnated silica gel plates. XE-60 is utilized in the GC method, and a column packed with NH 210 micrometers is used in the LC separation. Analyses were carried out on various commercial samples of N-phenyl-alpha-naphthylamine that were to be used as an antioxidant in aircraft engine lubricants. (Author)
