A complex of N,N'-ethylenebis(salicylideneiminato)diaquochromium(III) chlor
ide, [Cr(salen) (H2O)(2)]Cl as a model of glucose tolerance factor (GTF) wa
s characterized and its decomposition mechanism was studied by TG. The IR s
pectrum of the product of thermal decomposition was examined for the first
stage. Kinetic results were obtained from the analysis of TG and DTG curves
with four different methods. (C) 2000 Elsevier Science B.V. All rights res
