Analysis of 2,2-di(p-oligooxyethylenephenyl)propane by gas chromatography and gas chromatography—mass spectrometry

Abstract Gas chromatography and gas chromatography—mass spectrometry were used to analyse polydisperse mixtures of diols containing up to ten oxyethylene groups. The products were analysed as their trimethylsilyl derivatives. Arithmetic retention indices were determined for the diol homologues. The mass spectra of the trimethylsilyl derivatives of the compounds investigated are discussed.
