METHOD FOR DETERMINING CONCENTRATION OF AIRCRAFT ENGINE CORROSION PREVENTIVE COMPOUND IN A PRESERVATIVE-LUBRICATING OIL MIXTURE

Abstract

Evaluation of a spectrophotometric procedure for measuring the light transmission values of a tracer-dye additive at a characteristic wavelength was undertaken, since colorimetric equipment is normally available at the various O+R laboratories. The selected tracer-dye must be metal-free and soluble in the preservative compound and in the lubricating oil-preservative mixture. The specific absorption wavelength of the tracer-dye additive would then provide a means of quantitative determination of the preservative concentrate without interference by contaminants in the used engine oil. It was found that Blue Mist Dye fulfilled these requirements. The transmission values of the preservative compound-tracer dye-lubricating oil mixtures are given. The percentage of preservative compound derived therefrom is in very close agreement with the known concentration in the mixtures tested. The color stability of the tracer- dye is considered to be quite satisfactory.
