Özet:

 

Cadmium(II) complexes with 3-(6H-dibenzo[b,e] thiepin-11-ylidene) propyl dimethyl amine chloride (dot) and 2-diphenyl methoxy--N,N-dimethylamine   hydrochloride (dp) were synthesised and characterised by reflectance,   IR, 1H NMR, magnetic moments and conductivity measurements. The new   complexes  studied for kinetics of thermal degradation by   thermogravimetric analyses (TGA) and derivative thermogravimetric   studies (DTG) in a static nitrogen atmosphere at a heating rate of 10°C   min-1. The kinetic and thermodynamic parameters such as energy of   activation (Ea), frequency factor (lnA), enthalpy (D H), free   energy (D H), and entropy (D S) evaluated. The energy   of activation values for the degradation of (dot) and (dp) complexes were   found to be in the range 22.3-125.4 kJ mol-1.
