Gas chromatographic determination of tributyl phosphate, dibutyl phosphate and butyl phosphate in kerosene solutions

Abstract

A gas chromatographic procedure has been developed for the determination of tributyl phosphate (TBP), dibutyl phosphate (HDBP) and butyl phosphate (H₂MBP) in kerosene solutions. The last two compounds were converted into their methyl esters by reaction with a solution of diazomethane in diisopropyl ether prior to analysis. The same procedure was applied to the determination of HBDP and H₂MBP produced from gamma irradiation of the 30% TBP–kerosene–3 mol dm^–3 HNO₃ system.
