Kinetics of Thermal Decomposition of 1,1-Bis(Methoxy-NNO-Azoxy)-3-Nitro-3-Azabutane.

The thermal decomposition of 1,1-bis(methoxy-NNO-azoxy)-3-nitro-3-azabutane is studied under isothermal and nonisothermal conditions. The heats of its melting and thermal decomposition are 29.1 kJ/mol (7.0 kcal/mol) and 387 kJ/mol (92.5 kcal/mol), respectively. The composition of gaseous products of thermal decomposition is analyzed. The reaction takes place autocatalytically. The reaction center in the molecule of the studied substance is the diazene oxide group. The mechanism of the process is proposed. The limiting stage of the reaction includes a five-membered cyclic transition state. [ABSTRACT FROM AUTHOR]
