THE THERMODYNAMIC PROPERTIES OF 2-AMINOBIPHENYL

Measurements leading to the calculation of the ideal-gas thermodynamic properties for 2-aminobiphenyl are reported. (The Chemical Abstracts name and registry number are; [1,1′-biphenyl]-2-amine and [90-41-5].) Experimental methods included combustion calorimetry, adiabatic heat-capacity calorimetry, comparative ebulliometry, inclined-piston gauge manometry, and differential-scanning calorimetry (d.s.c.). Standard entropies, enthalpies, and Gibbs energies of formation were derived for the gas for selected temperatures between 298.15 K and 800 K. The critical temperature and critical density were determined for 2-aminobiphenyl with the d.s.c., and the critical pressure was derived. The experimental critical properties are compared with those derived from estimation methods. © 1991 Academic Press Limited All rights reserved.
