Thermogravimetry (TG) and differential thermogravimetry
(DTG) have been applied to the investigation of the thermal
behavior of six mixed ligand complexes of Ni(II) and Cu(II)
comprising the Schiff bases: o-hydroxyacetophenoneethanolimine
(OHAE), N-salicylidene-o-iminophenol (SOP) and N-salicylideneo-
toluidine (SOT) as well as morpholine (Morph) and certain
azoles. The azoles used are: 2-amino-thiazole (2-Atz),
benzothiazole (Btz), 2-methylbenzothiazole (2-Mbtz), 3-methyl-2-
selenoxobenzothiazole (3-Msbtz) and thiabendazole (Tbdz).
Heating the compounds first results in a release of the morpholine
or the azoles. Kinetics of the decomposition reactions were studied
using non-mechanistic equations.
