The thermodynamic properties of dibenzofuran

Article abstract of DOI:10.1016/0021-9614(90)90157-L

Measurements leading to the calculation of the ideal-gas thermodynamic properties for dibenzofuran are reported.Experimental methods included combustion calorimetry, adiabatic heat-capacity calorimetry, comparative, ebulliometry, inclined-piston manometry, and differential scanning calorimetry.Entropies, enthalpies, and Gibbs energies of formation were derived for the ideal gas for selected temperatures between 298.15 K and 720 K.The critical temperature and critical density were determined with a differential scanning calorimeter, and the critical pressure was derived.These are the first reported experimental critical properties for dibenzofuran.Measured combustion enthalpies, vapour pressures, critical properties, and ideal-gas entropies are compared with literature values.
