THERMODYNAMIC PROPERTIES OF PYRIDINE .2. COMPARISONS OF NEW RECOMMENDED VALUES WITH THE LITERATURE

Thermodynamic properties of pyridine (Chemical Abstracts registry numb er 110-86-1) are reviewed, and detailed comparisons between literature values and new recommended values of this research are provided. Prop erties reviewed are condensed- and gas-phase molar heat capacities, th e molar enthalpy of combustion, vapor pressures, densities, critical p roperties, virial coefficients, molar enthalpies of vaporization, and molar thermodynamic properties derived from assigned vibrational spect ra. In a companion paper to this review, new vapor pressures, high-tem perature molar heat capacities, and densities are reported which show that previously assessed values for pyridine require revision. Recomme ndations are made for values of all properties reviewed. Thermodynamic consistency between properties is emphasized. (C) 1996 Academic Press Limited
