“…At a concentration of 69.2 wt %, it forms a maximum-boiling azeotrope with water. The azeotropic mixture boils at 121.8 C. Pure anhydrous nitric acid boils at 83 -87 C; the reason a range of boiling points are cited in the literature is that the acid decomposes on heating [4]:…”

ChemInform Abstract In the course of investigations concerning the corrosion resistance of aluminum materials in highly concentrated nitric acid the thermal decomposition of this acid is observed at atmospheric pressure between 0 and 60 rc C for up to 273 d. The reversible decomposition reaction, which is shown in the scheme, is second order with respect of HNO3. The rate and equilibrium constants are determinedby evaluation the kinetic runs. The activation energy is found to be -134 kJ/mol.
