✦ Synopsis
The standard (p°= 0.1 MPa) molar enthalpies of formation for crystalline 2,6-dimethylquinoline, 2,6-(CH3)2-C9H5N, and 2,7-dimethylquinoline, 2,7-(CH3)2-C9H5N, at the temperature T=298.15 K, were derived from the standard molar energies of combustion, in oxygen, measured by static-bomb calorimetry. The standard molar enthalpies of sublimation, at T=298.15 K, were measured by microcalorimetry.
