    Description / Table of Contents: Studies on the Tautomerism of p-Substituted 4-Phenyl-azo-1-naphtholesBy means of UV-Vis spectroscopy the azo-hydrazone tautomerism of 4′-substituted 4-phenylazo-1-naphtholes has been studied in different solvents as well as in polyamide substrates. The analytical procedure used gives more reliable values than formerly described methods.The amount of azo and hydrazone form, respectively, and the long-wavelength absorption maxima are given.
    Notes: Die Tautomerieverhältnisse bei einigen p-substituierten 4-Phenylazo-1-naphtholen des Typs 1 werden UVS-spektroskopisch in verschiedenen Lösungsmitteln und in Poly-amidfolie untersucht. Das dabei angewendete Auswerteverfahren führt zu zuverlässigeren Tauto-merengehalten als bisher in der Literatur beschrieben.Die längstwelligen Absorptionen für die Azo- und Hydrazonform in verschiedenen Lösungs-mitteln und auf Polyamidsubstraten sowie die jeweiligen Hydrazongehalte werden angeführt.
