    Description / Table of Contents: Zusammenfassung Die DT- und TG- Analyse von acht Derivaten von 1,4-bis-(5′-Hydroxy-7′-sulpho-2′naphthyl)-benzoldiamid zeigte, dass diese Verbindungen mit einem Maximum im Temperaturbereich 280–330°C einen eindeutigen exothermen Effekt aufweisen. Derivate mit 4-Nitroanilin-2-sulfonsäure zeigen eine explosionsartige Zersetzung im Temperaturintervall 255–265°C und 285–290°C, was sich in den TG-Kurven in einer großen Stufe wiederspiegelt. Die Thermoanalyse von Bisazopigmenten ermöglicht eine Ermittlung ihrer Anwendbarkeit für höhere Temperaturen.
    Notes: Abstract The differential-thermal and thermogravimetric analysis of eight derivatives of 1,4-bis-(5′-hydroxy-7′-sulpho-2′naphthyl)-benzenediamide showed that these compounds have a marked exothermic effect, with maxima in the temperature range 280–330°C. The derivative of 4-nitroaniline-2-sulphonic acid were found to undergo a blast-like decomposition in the temperature intervals 255–265°C and 285–290°C, which is reflected by large steps in their TG curves. The thermal analysis of disazo pigments permits determination of their applicability at higher temperatures.
