Abstract

The thermal transformations of a number of modelo-amic acids were investigated by thermogravimetric analysis (TG). The TG data pointed to cyclodehydration of the amic acids and accompanying thermal degradation processes. TG in combination with mass-spectrometric thermal analysis provided sufficient information for the description of these processes on both qualitative and quantitative levels.

Zusammenfassung

Die thermischen Umwandlungen einer Reihe von Modellverbindungen dero-Amicsäuren wurden thermogravimetrisch untersucht. Die TG-Daten weisen auf eine Cyclo-dehydratisierung der Amicsäuren und parallel verlaufende thermische Zersetzungsprozesse hin. Die Thermogravimetrie liefert zusammen mit der massenspektrometrischen thermischen Analyse genügend Informationen zur Beschreibung dieser Prozesse sowohl auf qualitativer wie auch auf quantitativer Ebene.

Резюме

Методом термогравим етрии (ТГА) исследован ы термические превращ ения ряда модельных орто-а мидокислот. По данным ТГА изучены циклодегидратация а мидо-киспот и сопутствующие ей пр оцессы термодеструк ции. Показано, что ТГА в соч етании с масс-спектрометрич еским термическим ан ализом дает достаточную информа цию для описания этих процес сов как на качественн ом, так и на количественном уров не.
