A comprehensive study of thermodynamic properties of trans-2-cyclohexylcyclohexanol (t-2CCOL) was carried out in this work. The subject compound is a by-product from the synthesis of 2-phenylphenol. The standard molar enthalpy of combustion of t-2CCOL, found by the bomb calorimetry method, DcH°m(cr,298.15 K) = -(7388.05 2 1.37) kJ•mol -1 , and the standard molar enthalpy of formation DfH°m(cr,298.5 K) = -(478.25 2 2.13) kJ•mol -1 . The molar sublimation and vaporization enthalpies of t-2CCOL were measured with a heat-conduction differential microcalorimeter: D g cr H°m(319.5 K) = (98.56 2 0.52) kJ•mol -1 ; D g l H°m(345.8 K) = (80.31 2 0.34) kJ•mol -1 . Vapour pressure of t-2CCOL was measured by the integral effusion Knudsen method in the temperature range 293 K to 325 K for crystal: ln(p/Pa) = (37.30 2 0.22) -( 116162 69)•T -1 , and in the temperature range 328 K to 364 K for liquid: ln(p/Pa) = (34.41 2 0.44) -(10013 2 150)•T -1 . The heat capacity of t-2CCOL was measured by the vacuum adiabatic calorimetry (T = 5 K to T = 338 K). The fusion temperature of t-2CCOL is 325.8 K, and the molar enthalpy of fusion is DfusH°m = (14.515 2 0.029) kJ•mol -1 . Standard molar thermodynamic functions of t-2CCOL in the crystalline state at T = 298.15 K were obtained on the basis of these measurements: C°p,m = (248.68 2 0.99); D T 0 S°m = (263.85 2 1.18); D T 0 H°m/T = (130.52 2 0.51); F°m = (133.33 2 1.29) J•K -1 •mol -1 .
