Molar enthalpies of vaporization of a series of six 1,3-alkanediols were obtained from the temperature dependence of the vapor pressure measured by the transpiration method. A large number of the primary experimental results on temperature dependences of vapor pressures have been collected from the literature and have been evaluated in order to derive vaporization enthalpies at the reference temperature 298.15 K. The experimental enthalpies of vaporization were checked for internal consistency. New experimental results together with those selected from the literature have been recommended for thermochemical calculations.
