Calorimetrically determined values of the enthalpy and entropy of pure cis- and trans-hexahydroindan were used to calculate the thermodynamic properties and isomerization equilibrium mole fractions of the isomers in liquid and vapor phases. Experimental results are presented for heat capacities of the condensed phases from 12 deg to 390 deg k, enthalpies and entropies of fusion and solid-solid transitions, triple-point temperatures, sample purities, vapor pressures from 0.3 to 2025 torr, and derived thermodynamic functions [g8(t)-h deg (0)]/t, [h8(t)-h deg (0)]/t, [h8(t)-h8(0)], and s8 (t) at selected temperatures in solid, liquid, and vapor phases. Calculated isomeric equilibrium mole fractions for the reaction: trans-hexahydroindan-cis-hexahydroindan, based on the calorimetric measurements, are compared with mole fractions observed in catalyzed reaction equilibrium studies.
