Thermoanalysis and catalytic study of transition metals acetylacetonates

Abstract The T, TG, DTG, and DTA curves of eight transition metals acetylacetonates, namely, those of Cr(II), Co(II), Cu(II), Fe(III), Mn(II), Ni(II), V(III) and VO(III) have been studied under air static and inert dynamic nitrogen or argon gases. Under the letter, their decomposition temperatures were increased by about 30–50 C. Their roles as promoting catalysts for the thermal decomposition of barium perchlorate trihydrate (BP.3H2O) have been investigated as well as the kinetic parameters, such as n, E, and log Z, of the decomposition of them. Evolved gaseous products (methane, acetylacetone, carbon dioxide and water) have been detected by GC. Solid intermediates and final products have been identified by XRD methods. Eight DIG and eight DTA curves (Figures 1 and 2) have been established to characterise each of the above metals acetylacetonates.
