Condensed-phase heat-capacity studies and derived thermodynamic properties for six cyclic nitrogen compounds

Condensed-phase heat capacities and enthalpies were determined at temperatures from near 10 to 400 K for N-methylpyrrole, 2,5-dimethylpyrrole, piperidine, 2-methylpiperidine, 4-methylpyridine, and N-methylcarbazole, and were used to provide the Gibbs energy, enthalpy, entropy, and heat capacity alon...

Description
Summary:Condensed-phase heat capacities and enthalpies were determined at temperatures from near 10 to 400 K for N-methylpyrrole, 2,5-dimethylpyrrole, piperidine, 2-methylpiperidine, 4-methylpyridine, and N-methylcarbazole, and were used to provide the Gibbs energy, enthalpy, entropy, and heat capacity along the vapor-saturation line at temperatures from 0 to 400 K. The corresponding ideal-gas thermodynamic properties were derived using available vapor pressures and enthalpies of vaporization. The Gibbs energy, enthalpy, and entropy of formation were derived for the ideal gas at selected temperatures with available enthalpies of combustion.
