Abstract

The effects of active (carbon dioxide and carbon monoxide) and neutral (helium, argon and nitrogen) atmospheres on the course of thermal decomposition of oxalates have been studied and compared. A mechanism of thermal decomposition has been proposed on the basis of the results obtained, the first stage of which consists in a heterolytic dissociation of the C-C bond, with the formation of carbon dioxide and the CO 2 2− anion.

Zusammenfassung

Die Effekte von aktiven (Kohlendioxid und Kohlenmonoxid) und neutralen (Helium, Argon, Stickstoff) Atmosphären auf den Verlauf der thermischen Zersetzung von oxalaten wurden untersucht und miteinander verglichen. Aus den erhaltenen Ergebnissen wird ein Mechanismus der thermischen Zersetzung abgeleitet, dessen erster Schritt die heterolytische Dissoziation der C-C-Bindung unter Bildung von CO2 und des CO 2 2− -Anions ist.

Резюме

Изучено и сопоставле но влияние активной атмосферы (моно- и двуо кись углерода) и инертной (гелий, аргон и азот) на ход термичес кого разложения оксалато в. На основании полученных результа тов предложен механи зм термического разлож ения, первая стадия которого вызвана гет еролитической диссо циацией связи C-C с образованием двуокиси азота и аниона CO 2 2− .
