The thermodynamic properties of quinoline and isoquinoline

Enthalpies of combustion, vapour pressures, and enthalpies of sublimation of 2-phenylquinoline and 2,2′-biquinoline

“…(6) With the values of the standard molar enthalpies of formation for quinoline (200.54 2 0.94) kJ·mol −1 , (22) 2,2'-bipyridine (267.9 2 3.0) kJ·mol −1 , (9) and pyridine (140.4 2 0.7) kJ·mol −1 , (23) then D r H°m = (11.6 2 5.3) kJ·mol −1 for equation (6). This endothermicity is probably due to an increase of non-planarity of 2,2'-biquinoline compared with 2,2'-bipyridine, which seems to have a planar trans conformation.…”

The thermodynamic properties of 2-methylaniline and trans-(R,S)-decahydroquinoline

“…(6,7) Within the heat-capacity results the weighting factors were proportional to the square of the mass of sample used in the measurements. ( 1 7) with Pc = 305 kg·m -3, T c = 716.5 K, and the acentric factor ro "" 0.386.…”

The thermodynamic properties of 2-methylaniline and trans-(R,S)- decahydroquinoline

“…heat-capacity and enthalpy measurements were made with a calorimetric system that has been described previously. (6,7) The calori~eter characteristics and sealing conditions are given in . ' (35) showed that the Cox equation (36) The Cox equation in the form:…”
