Abstract

Adsorption isotherms and differential heats of adsorption of tetrahydropyrrol (THP) and cyclopentane CP), as well as THP and methanol mixtures (mole ratio 1∶1, 1∶2 and 1∶4) on the graphitized carbon black Sterling MT surface were determined. The influence of dilution of [THP] on its ability to undergo homomolecular association was tested. Even 1∶4 dilution of THP does not prevent is association. Methanol strongly interacts with THP in the mixed adsorbed layer forming heteromolecular associates.

Zusammenfassung

An grafitierter Rußoberfläche wurden die Adsorptionsisothermen und die differentiellen Adsorptionswärmen von Tetrahydropyrrol (THP) und Cyclopentan (CP) sowie von THP/Methanol-Gemischen (Molverhältnis 1∶1, 1∶2 und 1∶4) bestimmt. Der Einfluß des Verdünnens von THP auf seine Fähigkeit, homomolekulare Assoziationen einzugehen, wurde untersucht. Selbst eine Verdünnung von 1∶4 kann die Assoziation von THP nicht verhindern. In der gemischten adsorbierten Schicht tritt Methanol mit THP in starke Wechselwirkungen, wobei heteromolekulare Assoziationen gebildet werden.
