The standard enthalpy of formation and the low-temperature heat capacity of ethylferrocene

The temperature dependence of the heat capacity of ethylferrocene was studied in the temperature range 7-301 K with the use of an adiabatic vacuum calorimeter. The temperature, enthalpy, and entropy of fusion were determined, and the thermodynamic functions of the compound in the crystalline and liquid states were calculated at temperatures from 0 to 300 K. The enthalpy of combustion of ethylferrocene was determined in an isothermic-shell calorimeter with a stationary bomb. The standard thermodynamic functions of formation of ethylferrocene in the condensed state at 298.15 K were calculated.
