Combined Gas-Liquid Chromatographic Mass Spectrometric Analysis of Some Commercial Aryl Phosphate Oils

Abstract
Five commercial samples of synthetic aryl phosphate oils, which are widely used as fire retardant hydraulic fluids and as flame retardant plasticizers, have been analyzed by combined gas-liquid chromatography/mass spectrometry (GLC/MS). Each sample contained at least 4 isomers of aryl phosphate esters. The peaks were identified by a close examination of the mass spectral data and, wherever possible, by comparing retention times of the peaks with those of either the purchased or synthesized compounds. One aryl phosphate hydraulic fluid contained a small amount of a hydrocarbon. The results indicate that most of the aryl phosphate esters in the commercial samples were formed from phenol, cresols, xylenols, and other alkyl phenols. No free phenols could be detected in the samples analyzed.
