PREPARATION AND THERMAL STUDY OF NEW COMPLEXES OF SALICYLIDENE-2-AMINOTHIOPHENOL SCHIFF BASES
摘要:
New complexes of the Schiff base salicylidene-2-aminothiophenol with VO(IV), Co(II), Ni(II), Cu(II) and Zn(II) have been synthesized and studied by thermogravimetric analysis and a general scheme of thermal decomposition of these complexes is proposed. The thermal dehydration and decomposition of these complexes were studied kinetically using the integral method applying the Coats-Redfern equation. It was found that the thermal decompositions of the complexes follow first order kinetics. The thermodynamic parameters of the decomposition are also reported.
