a The saturation vapor pressure (in Pa) of the amine
at 298 K.3,5
b The gaseous basicity (in kJ∙mol−1)
at 298 K.10
c The aqueous base hydrolysis constant (in
mol∙kg−1) of the amine at 298.15 K.3
d The solid/gas equilibrium dissociation constant (in
Pa2) of the nitrate salt of the amine at 298.15
K.3
e The transitional temperature (in K) of nitric acid
condensation, defined as the temperature at which the moles of total
nitrate in the condensed phases equals to 5% of the initial moles of
nitric acid and determined in this study. Details on uncertainty
estimations are in the Supporting Information (Table S1).
f classified based on the Tc of
the amine: Group I amines with Tc ≤ 278 K and
Group II with Tc > 288 K.
