3 Previous Findings Jun Gao and Maria Papadaki, 2006 Isothermal HEL SIMULAR Calorimeter The highly exothermic H 2 O 2 decomposition starts at temperatures above 50 o C. Hydrogen peroxide is catalytically and thermally decomposed. However, the rate of the thermal decomposition is insignificant. The catalytic decomposition of hydrogen peroxide is slower in the N oxidation reaction. THE N OXIDATION OF ALKYLPYRIDINES 3

21 The catalyst accelerates the decomposition of 2-methylpyridine-Noxide. 2-methylpyridine has a detrimental effect on the rate of decomposition of both hydrogen peroxide and 2-methylpyridine-Noxide. CONCLUSIONS 2-methylpyridine-N-oxide affects the rate of hydrogen peroxide decomposition. There are two stages in the decomposition: Oxygen removal from 2- methylpyridine-n-oxide and 2-methylpyridine decomposition. Further research is needed: To determine the decomposition products To investigate similar behaviors of other alkylpyridines. 16
