ENTHALPIES OF COMBUSTION, VAPOR-PRESSURES, AND ENTHALPIES OF SUBLIMATION OF 5-AMINO-6-NITROQUINOLINE AND 4-AMINOQUINALDINE

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 c alorimetry for 5-amino-6-nitroquinoline and 4-aminoquinaldine, from wh ich the standard molar enthalpies of formation of both compounds, in t he crystalline state, were derived. The standard molar enthalpies of s ublimation Delta(cr)(g)H(m)degrees of the same compounds were derived from the Knudsen effusion measurements of the vapour pressures as a fu nction of the temperature. [GRAPHICS] The derived standard molar entha lpies of formation in the gaseous state are shown to fit a group addic tivity scheme. (C) 1998 Academic Press.
