Abstract

The molar excess enthalpies of binary mixtures of 2,4-lutidine with isopropanol, isobutanol and 2-butanol at 293.15 and 303.15 K, and withtert-butanol at 303.15 K, were measured over the whole composition range.

The absolute values of all the molar excess functions were found to increase in the order: isobutanol<2-propanol<2-butanol<tert-butanol.

Zusammenfassung

Die molaren Überschußenthalpien binärer Mischungen von 2,4-Lutidin mit Isopropanol, Isobutanol und 2-Butanol wurden bei 293.15 und 303.15 K, sowie mittert-Butanol bei 303.15 K im ganzen Zusammensetzungsbereich gemessen. Es zeigte sich, daß die absoluten Werte sämtlicher molarer Überschußfunktionen in der Reihenfolge Isobutanol <2-Propanol<2-Butanol<tert-Butanol zunehmen.

Резюме

Измерены молярные из быточные энтальпии в о всей области смешний бйнарных смесей 2.4-лутидина с изо пропанолом, изобутан олом и 2-бутанолом при 293.15 К 303.15 К, а также с трет-бутан олом при 303.15 К. Найдено, чт о абсолютные значения всех молярных избыточных энтальпий увеличива ются в ряду изобутанол <2-пропанол <2бутанол <трет-бутанол.
