Possible precursors and products of deep hydrodesulfurization of gasoline and distillate fuels IV. Heat capacities, enthalpy increments, vapor pressures, and derived thermodynamic functions for dicyclohexylsulfide between the temperatures (5 and 520) K ☆ ☆☆

Abstract Measurements leading to the calculation of the standard thermodynamic properties for gaseous dicyclohexylsulfide (Chemical Abstracts registry number [7133-46-2]) are reported. Experimental methods include adiabatic heat-capacity calorimetry, and inclined-piston gauge manometry combined with earlier reported measurements of combustion calorimetry, vibrating-tube densitometry, comparative ebulliometry, and differential-scanning calorimetry (d.s.c.). Critical properties are estimated for dicyclohexylsulfide. Standard molar entropies, standard molar enthalpies, and standard molar Gibbs free energies of formation are derived at selected temperatures between (298.15 and 520) K.
