Thermal Decomposition of 2-Nitrobenzoic Acid

Journal of Chemical Technology & Biotechnology, 1997
The thermal decomposition of 2-nitrobenzoic acid is investigated by means of adiabatic and quasi-isothermal calorimetry. The decomposition process develops according to zero order kinetics which gives substantial support to the intervention of vapour-phase reaction. The apparent activation energy of 144.8 kJ mol(-1) is evaluated.
