Molar enthalpies of vaporization of cyclic alkyl carbonates: ethylene carbonate, propylene carbonate, butylene carbonate, and glycerine carbonate were obtained from the temperature dependence of the vapour pressure measured by the transpiration method. A large number of the primary experimental results on temperature dependences of vapour pressures have been collected from the literature and have been treated uniformly in order to derive vaporization enthalpies of alkylene carbonates at the reference temperature 298.15K. This collection together with the new experimental results has been used for the selection of the reliable data sets for each compound under study. Experimental vapour pressure data from various literature sources were reviewed and regressed together with data developed in this work. The resulting correlations for vapour pressure of cyclic alkylene carbonates are recommended for use over a temperature range fromambient to the normal boiling point. Consequently, these correlations were used to derive recommended molar enthalpy of vaporization values at 298.15 K.
