The Heat
Capacity and Thermodynamic Functions of Ferrocenyl-Methanol
Abstract
The
low-temperature heat capacity of ferrocene-methanol, C5H5FeC5H4CH2-OH (FM),
has been measured by adiabatic calorimetry. The triple point temperature, the
enthalpy of fusion, and the purity of the substance under study have been
obtained. Ideal gas thermodynamic functions of FM: absolute entropy and change
of the enthalpy at T=298.15 K were derived from the heat capacity data
and literature values of the saturation vapour pressure and the enthalpies of
sublimation. The ideal gas heat capacity the absolute entropy, and the enthalpy
of formation of FM were calculated by empirical difference method at T=298.15
K. The experimental and estimated values of the thermodynamic function conform
within errors limits that proves their reliability.
