Abstract (EN): The standard (p degrees = 0.1 MPa) molar enthalpies of formation, in the liquid phase, of 2-, 3- and 4-chloroanisoles, at T = 298.15 K, were derived from their standard massic energies of combustion, in oxygen, to yield CO2(g) and HC1 center dot 600H(2)O(l), measured by rotating bomb combustion calorimetry. The Calvet high-temperature microcalorimetry technique was used to measure the standard molar enthalpies of vaporization of these compounds. [GRAPHICS] From these two sets of experimental values, the standard molar enthalpies of formation in the gaseous phase, at T = 298.15 K, were derived, compared with the same parameters estimated by the Cox scheme and interpreted in terms of molecular structure.
