Abstract

The thermal decomposition of methylammonium perchlorate (MAP) has been studied under isothermal and non-isothermal conditions. Differential thermal analysis of MAP showed, in addition to the exotherm due to decomposition, another exotherm at 408° which was observed for the first time. Chemical analysis and the infrared spectrum of the residue left behind after the decomposition proved it to contain NH4ClO4. The results have been explained on the basis of a methyl group transfer in addition to proton transfer in the decomposition process.

Résumé

On a étudié la décomposition thermique du perchlorate de méthylammonium (PMA) en conditions isothermes et anisothermes. L'analyse thermique différentielle des perchlorates de méthylammonium a montré, en plus du phénomène exothermique dû à la décomposition, un second pic exothermique à 408°C, observé pour la première fois. L'analyse chimique et le spectre infrarouge du résidu de décomposition ont établi la présence de NH4ClO4. Les résultats s'expliquent bien par le transfert d'un groupe méthyle accompagné d'un transfert de proton lors du processus de décomposition.

Zusammenfassung

Die thermische Zersetzung von Methylammonium-Perchlorat (MAP) wurde unter isothermen Bedingungen untersucht. Die DTA zeigte neben der exothermen Spitze für die Zersetzung noch eine weitere bei 408°, über die noch nie berichtet wurde. Die Analyse des Zersetzungsrückstandes ergab NH4ClO4. Diese Ergebnisse wurden durch einen zusätzlich zur Protonenübergabe ablaufenden Methylgruppentransfer erklärt.

Резюме

Было изучено термиче ское разложение перклората метиламм ония (МАП) при изотермических и не и зотермических услов иях. Дифференциальный те рмический анализ этого соединения пок азал наряду с экзотер мой, обусловленной разло жением, наличие другой экзотермы при 408°, которая наблюдалас ь нами впервые. С помощью хим ического анализа и инфракрасн ых спектров было уста новлено, что остаток после разлож ения содержит NH4ClO4. Полученные резуль таты объяснены совме стным переносом метальной группы и протона в про цессе разложения.
