Abstract:Molar enthalpies of vaporization of 2-Br-phenyl isobutyl ether, 3-Br-phenyl isobutyl ether, 4-Br-phenyl isobutyl ether, and 2-Br-4-Me-phenyl isobutyl ether were obtained from the temperature dependence of the vapor pressure measured by the transpiration method. The measured data sets were successfully checked for internal consistency. The values of enthalpies of vaporization and vapor pressures of ortho-, meta-, and para-substituted benzenes are discussed in the context.
