Öğe Thermal decomposition kinetics of anilino-p-chlorophenylglyoxime complexes of cobalt (II), nickel (II) and copper (II)(SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY, 2003) Arslan, H; Kulcu, N; Pekacar, AIThe Co(II), Ni(II) and Cu(II) complexes of anilino-p-chlorophenylglyoxime were synthesised. The thermal behaviour of all complexes was studied by DTA and TG. It was found that pyrolytic decomposition occurs with melting in metal complexes and that metal oxides remain as final products of the metal complexes. A GC-MS combined system was used to identify the products during pyrolytic decomposition. The pyrolytic end products were identified by x-ray powder diffraction. The orders, n, the activation energies, E*, the pre-exponential factors, A, and the entropies, DeltaS*, of thermal decomposition reactions were derived from thermogravimetric and differential thermogravimetric curves. The, kinetic analysis of the thermogravimetric data was performed by using the Coats-Redfern and Horowitz-Metzger methods.Öğe Thermal studies of p-toluidino-p-chlorophenylglyoxime and of some corresponding Ni(II), Cu(II) and Co(II) complexes(ELSEVIER SCIENCE BV, 1999) Arslan, H; Ozpozan, N; Ozpozan, TThe thermal behaviour of p-toluidino-p-chlorophenylglyoxime (pTpCPG) and its Cu(II), NI(TI), and Co(LI) complexes have been studied by DTA and TG. It was found that pyrolytic decomposition undergoes with melting in both Ligand and its metal complexes and metal oxides remained as end products of the metal complexes. The ligand decomposes in two stages through two different mechanisms and the metal chelates undergo decomposition in three stages. GC-MS combined system was used to identify the products during pyrolytic decompositions. The pyrolytic end products were identified by X-ray powder diffraction. (C) 1999 Elsevier Science B.V.
