A kinetic study of the thermal degradation of 3-methylaminopropylamine inside AlPO4-21

Kinetics of the thermal decomposition of 3-methylaminopropylamine which was used as a structure-directing agent in the synthesis of AlPO4-21 has been studied under isothermal and non-isothermal conditions. The decomposition is a single-step reaction occurring in the 573-663 K range. It is a phase-boundary-controlled process, described by the 'F2/3, R3' kinetic model. The activation energy values obtained under the non-isothermal and isothermal conditions lie in the 173-151 kJ mol(-1) range.
