Abstract:

Measurement of the thermal properties of a mixture of ethylenimine and its dimer near the eutectic composition has provided needed information for interpreting the premelting region of pure ethylenimine. Tables of values for enthalpy of formation, Gibbs energy of formation, and logarithm of the equilibrium constant of formation of ethylenimine were calculated. Molal thermodynamic functions for the condensed phases of 1,2-diaminoethane and 1,2- diaminopropane were calculated from low-temperature calorimetric measurements. The thermochemical properties of isobutylamine were measured in order to further define C-N bond energy in amines and diamines. Correlations of the thermodynamic properties of hexafluorobenzene were completed from 0 to 1500K.
