| Abstract: | Molar enthalpies of vaporization, ΔlgHm0, of 1-methyl-naphthalene, 1-chloro-napthalene, 2-chloro-naphthalene, 1-bromo-naphthalene, 2-bromo-naphthalene, and 1-iodo-naphthalene, as well as molar enthalpies of sublimation, ΔsgHm0, of 2-chloro-naphthalene and 2-bromo-naphthalene have been obtained from the temperature dependence of the vapor pressure determined with the transpiration method. These values and the correlation gas-chromatography method, based on the Kovat’s index, have been used to determine ΔlgHm0 and ΔsgHm0 of 2-iodo-naphthalene. Results obtained in this work have been compared with those from the literature and found consistent. |
