Title

Studies on Thermal Degradation of Oligo-2-[(4-morpholin-4-yl-phenyl)imino Methyl] Phenol and Oligomer-metal Complex Compounds

Abstract

Thermogravimetric studies of 2-[(4-morpholin-4-yl-phenyl) imino methyl]phenol (2-MPIMP), oligo-2-[(4-morpholin-4-yl-phenyl) imino methyl] phenol (O-2-MPIMP) and its oligomer-metal complex compounds were investigated by thermal analysis. Four kinetic methods were used to investigate the thermal decomposition of these materials. These investigated methods are those of Coats and Redfern (CR), MacCallum and Tanner (MC), van Krevelen (vK) and Madhusudanan, Krishnan and Ninan (MKN). The values of the apparent activation energies of thermal decomposition E a, the reaction order n, pre-exponential factor A, the entropy change ΔS *, enthalpy change ΔH *, free energy change ΔG *, obtained by the above-mentioned methods were all in good in agreement with each other. It was found that the thermal stabilities of the complexes follow the order Cu(II) > Co(II) > Zn(II) > Zr(IV) > Pb(II) > Cd(II).
