Abstract: In the present study, new quantitative structureeproperty relationships (QSPR) were presented to predict the normal boiling point (Tb), and enthalpy of vaporization of pure refrigerants at Tb (ΔHvb ). For developing these models, the experimental data of Tb for 192 pure components and the experimental data of ΔHvb for 180 pure components were used. For each ...
