The rates of dehydroxylation of smectites intercalated with the decomposition products of Ni(phen)3SO4 are from 2 to 4 times greater than those of clays without the heat-stable intercalate. These results suggest that the intercalated material, in keeping the clay sheets separated, provides a more ready avenue for water loss during the dehydroxylation process.

Резюме

Резюме

Скорости дегидроксилирования смектитов, насыщенных продуктами разложения Ni(фен)3SO4 от 2 до 4 раз выше, чем для глин без теплостойких прослоев. Эти результаты показы¬вают, что эти включения, разделяя слои глины, обеспечивают лучшие условия для потери воды в течение процесса дегидроксилирования.

Resümee

Resümee

Die Geschwindigkeiten der Dehydroxylierung von Smektiten mit eingelegten Zerfallsprodukten von Ni(phen)3SO4, sind 2 bis 4 mal höher als die von Tonerden ohne die hitzebeständigen Einlagen. Diese Resultate schlagen vor, daß das eingeschobene Material, indem es die Tonschichten separiert, einen besseren Weg für den Verlust von Wasser während des Dehydroxylierungsvorgang verschafft.

Résumé

Résumé

La rapidité de déhydroxylation de smectites intercalates avec les produits de decomposition de Ni(phen)3SO4 est de 2 à 4 fois plus élevée que celle d'argiles sans l'intercalate stable à réchauffement. Ces résultats suggèrent que la matière intercalée fournit un chemin plus favorable à la perte d'eau pendant le processus de déhydroxylation en maintenant séparées les couches argileuses.
