Abstract

The authors have measured the vapour pressure of the binary four systems, piperidin +1,4-dioxan, piperidin+tetrahydropyran, piperidin+tert-butyl methyl ether and N-methyl piperidin+tert-butyl methyl ether. The measurements were carried out using an isoteniscope built by J. Jose [1]. The vapour pressure, excess Gibbs free energies at 298.15 K, 303.15 K, 313.15 K, 323.15 K, 333.15 K and 343.15 K, are reported for these mixtures. The excess Gibbs free energies have been fitted to the Redlich-Kister equation.

Zusammenfassung

Von den Verfassern wurde der Gasdruck der vier binären Systeme Piperidin+1,4-Dioxan, Piperidin+Tetrahydropyran, Piperidin+tert-Butylmethy lether und N-Methylpiperidin+tert-Butylmethylether vermessen. Die Messungen wurden mittels eines von J. Jose [1] gebauten Isoteniskopes durchgeführt. Der Gasdruck und die Gibbs'schen freien Überschußenergien für 298.15 K, 303.15 K, 313.15 K, 323.15 K, 333.15 K und 343.15 K für diese Gemische wurden beschrieben. Die Gibbs'schen freien Überschußenergien wurden der Gleichung von Redlich-Kister angepaßt.
