Abstract (EN): The standard (p degrees = 0.1 MPa) massic energies of combustion Delta(c)u degrees at T = 298.15 K were measured by static bomb combustion calorimetry for 5-amino-6-nitroquinoline and 4-aminoquinaldine, from which the standard molar enthalpies of formation of both compounds, in the crystalline state, were derived. The standard molar enthalpies of sublimation Delta(cr)(g)H(m)degrees of the same compounds were derived from the Knudsen effusion measurements of the vapour pressures as a function of the temperature. [GRAPHICS] The derived standard molar enthalpies of formation in the gaseous state are shown to fit a group addictivity scheme. (C) 1998 Academic Press.
