The thermodynamic and thermophysical properties of 1‐ and 2‐butanamine, 2‐methyl‐1‐propanamine, 2‐methyl‐2‐propanamine, pyrrole, 1‐, 2‐ and 3‐methylpyrrole, pyridine, 2‐, 3‐, and 4‐methylpyridine, pyrrolidine, piperiodine, indole, quinoline, isoquinoline, acridine, carbazole, phenanthridine, 1‐ and 2‐naphthalenamine, and 9‐methylcarbazole have been evaluated. Recommended values are given for the following properties: normal boiling, freezing and triple point temperatures, critical constants, thermodynamic properties in the solid and liquid phases, vapor pressure, enthalpy of vaporization, density, second virial coefficients, and enthalpy of combustion. Ideal gas thermodynamic properties have been calculated by statistical mechanical methods.
