Verdampfungsgleichgewichte und Mischungswärmen in den Systemen Cyclohexan-n-Heptan und Methylcyclohexan–n-Heptan [PDF]
Zeitschrift für Naturforschung A, 1950 Abstract Wie kalorimetrische Messungen und Bestimmungen der Verdampfungsgleichgewichte zeigen, wird das System Cyclohexan-n-Heptan durch stark positive Mischungsenthalpie HE (endothermes Mischen), die praktisch (im Bereich um 20° C) nicht von der Temperatur abhängt, sowie durch positive Zusatzentropie S E (größere Mischungsentropie als ...
