techniques; TG, DTG, and DTA curves were recorded on a derivatograph (type Q-1500) using samples of 100 mg with α-Al 2 O 3 as reference material in static air atmosphere. From TG, DTA, and DTG curves, solid intermediate products are determined and confirmed
-obtained intermediates were dissolved in chloroform. The solvent was then evaporated under reduced pressure that resulted in the formation of yellowish-brown intermediate, which was further purified by TLC using precoated silica gel 60 F254 plates and flash column

estimation of product yields at intermediate stages of conversion.
A promising approach to specify thermodynamic solutions is the models of extreme intermediate states suggested at MESI. They develop the methodology of classical equilibrium

gradient between the solid catalyst and the surrounding gas, the existence of a self-acceleration process cannot be attributed to the reaction exothermicity; only the multiplication (branching) of the active intermediates on the catalyst surface can account

intermediates on the surface ( Fig. 1a ). This mechanism prevailed until Brady and Pettit [ 21 , 22 ] demonstrated the importance of adsorbed CH 2 species on the catalyst's surface. Brady and Pettit's work was refined by experimental investigation by Quyoum

Complexone III as an agent and Eriochrome black T as an indicator.
The IR spectra of the prepared zinc complex compounds and the solid intermediates of thermal decomposition were recorded on an AVATAR 330 FT-IR Thermo Nicolet spectrometer using KBr
on the thermal decomposition of transition metal amine complexes, not many studies has been reported to date with regard to the evolved gas analysis (EGA) during thermal decomposition and also in detecting the transient intermediates formed during
