Abstract
By means of non-isothermal DTA in its simple form the initial exotherm temperaturesT D of 2,4-dinitrotoluene, 2,6-dinitrotoluene, 2,4,6-trinitrotoluene, 1,5-dinitronaphtalene, 1,8-dinitronaphthalene and 1,4,5,8-tetranitronaphthalene have been determined. By application of the Piloyan method to these measurements, the activation energiesE arising from the decompositions of these compounds were established. The results are discussed from the point of view of the molecular structures of the polynitro compounds.
Résumé

Les énergies d'activationE de la décomposition de ces composés ont été déterminées à l'aide de la mé thode de Piloyan. Les résultats obtenus sont discutés sous l'aspect de la structure moléculaire de ces composés.
Zusammenfassung
Durch nicht-isotherme DTA in ihrer einfachen Form wurde der BeginnT D der Exothermen von 2,4-Dinitrotoluol, 2,6-Dinitrotoluol, 2,4,6-Trinitrotoluol, 1,5-Dinitronaphthalin, 1,8-Dinitronaphthalin, 1,4,5-Trinitronaphthalin und 1,4,5,8-Tetranaphthalin bestimmt. Durch Anwendung der Methode von Piloyan auf diese Messungen wurden die aus der Zersetzung o.a. Verbindungen herrührenden AktivierungsenergienE spezifiziert. Die erhaltenen Ergebnisse werden unter dem Aspekt der Molekularstruktur der untersuchten Polynitroverbindungen erörtert.
