| contents | Thermal degradation behaviour of some polydithiooxamide metal complexes M. A. Khalid H. Al-Maydama A. El-Shekeil A. Al-Karbouly Química complexes polydithiooxamide thermal behaviour thermal stability kinetic parameters The thermal decomposition behavior of the Fe(II), Co(II), Ni(II) and Zn(II) complexes ofpolydithiooxamide has been investigated by thermogravimetric analysis (TGA) at a heating rate of20°C min-1 under nitrogen. The Coats-Redfern integral method is used to evaluate the kinetic parametersfor the successive steps in the decomposition sequence observed in the TGAcurves. The processesof thermal decomposition taking place in the four complexes are studied comparatively as the TGAcurves indicate the difference in the thermal decomposition behavior of these complexes. The thermalstabilities of these complexes are discussed in terms of repulsion among electron pairs in the valenceshell of the central ion and electronegativity effects. 2006 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42931106 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.1 Vol.31 |
