Cycloheptane, Cycloöctane and 1,3,5-Cycloheptatriene. Low Temperature Thermal Properties, Vapor Pressure and Derived Chemical Thermodynamic Properties
TLDR
In this article, the entropy of cycloheptane, cyclooctane and 1,3,5-cyclohexatriene at 298.16/sup 0/K was derived from low temperature thermal properties and vapor pressure.Abstract:
From determinations of the low temperature thermal properties and vapor pressure of cycloheptane, cyclooctane and 1,3,5-cycloheptatriene, values of the entropy in the liquid and vapor states and the heat of vaporization, all at 298.16/sup 0/K, were obtained. These results and values of the heats of formation derivable from literature data were used to compute values of ..delta..Hf/sup 0/, ..delta..Ff/sup 0/, ..delta..Sf/sup 0/ and log/sub 10/ Kf for all three compounds in the liquid and vapor states at 298.16/sup 0/K. In the solid state the thermal behavior of each substance is complex; there are transitions between four different crystalline forms of cycloheptane, three of cyclooctane and two of 1,3,5-cycloheptatriene.read more
