Abstract
The absolute vapour pressures of three amino-alcohols were measured using the transpiration method. The consistent set of standard molar enthalpies of vaporization for eighteen amino-alcohols was evaluated using empirical and structure–property correlations. Correlation of vaporization enthalpies with normal boiling temperatures was established. Vaporization enthalpies of amino-alcohols obey the group-additivity rules. The averaged values of vaporization enthalpies were recommended as reliable benchmark properties for the heat management of CO2 capture technologies.
