Abstract

The ternary system containing H2C2O4 · 2H2O, NaHC2O4 · and Na2C2O4 was investigated. It was ascertained that the termal curves of the mixtures were not the algebraic sums of their component curves. All thermal decomposition stages were interpreted and the means of performing qualitative and quantitative analyses in the system were given.

Résumé

On a étudié le système ternaire contenant H2C2O4 · 2H2O, NaHC2O4 · H2O et Na2C2O4. On a établi que les courbes thermiques des mélanges ne correspondaient pas à la somme algébrique de leurs courbes composantes. On a interprété toutes les étapes de la décomposition thermique et donné les moyens d'effectuer des analyses qualitatives et quantitatives du système.

Zusammenfassung

Das H2C2O4 · 2 H2O, NaHC2O4 · H2O und Na2C2O4 enthaltende ternäre System wurde untersucht. Es wurde festgestellt, daß die thermischen Kurven der Gemische nicht den algebraischen Summen ihrer Komponentenkurven entsprachen. Sämtliche Stufen der thermischen Zersetzung wurden zugeordnet und die Möglichkeiten der Durchführung qualitativer und quantitativer Analysen im System angegeben.

Резюме

Исследована тройная система, содержащая Н2С2О4. 2Н2О, NaHC2O4. Н2О и Na2C2O4. Установлено, что т ермические кривые см есей не являются алгебраиче ской суммой кривых отдельных ком понент. Были объяснен ы все стадии термического разлож ения и даны пути проведения количественного и ка чественного анализов.
