✦ Synopsis

Trimethylsilyl derivatives of the alkylphosphonates and of certain aminoalkylphosphonates were found to be satisfactory for the characterization of these phosphorus compounds by gas chrom'atography and gas chromatography-mass spectrometry. The trimethylsilyl derivatives of the I-aminoalkylphosphonates were, however, not sufficiently stable for this purpose. In order to analyze these compounds satisfactorily, the amino group was converted into the N-acetyl derivative, acetone Schiff base, or isothiocyanate; trimethylsilyl ester formation was retained for the' phosphonate system. These derivatives, particularly the isothiocyanates, were stable and had good gas chromatographic and mass spectrometric properties.

Photoproducts resulting from illumination of a pyrene-chloroform solution using several light sources (sunlight, lamp, a pulsed laser) were analyzed by using gas chromatography (GC) and GC-mass spectrometry. The main photoproducts in chloroform were chloropyrene and pyrenecarboxaldehydes, and their
