Thermodynamic properties of pyridine—I. Vapor pressures, high-temperature heat capacities, densities, critical properties, derived thermodynamic functions, vibrational assignment, and derivation of recommended values
Measurements leading to the calculation of standard thermodynamic properties for pyridine (Chemical Abstracts registry number 110-86-1) are reported for temperatures from the triple-point temperature T tp=231.51 K to T=560 K. The standard state is defined as the ideal gas at the pressure p p= o=101....
