Kinetics of thermal dehydration of some bis-(4-aminosalicylato)-diaquo complexes of transition metal ions

Thermal Decomposition Kinetics of Ni(II) Chelates of Substituted Chalcones

“…9 Chalcones usually exhibit germicidal 10 bactericidal, 11 fungicidal 12 and carcinogenic activities. 13 In continuation of our earlier work [14][15][16][17][18][19] on thermal decomposition kinetics of metal chelates, the present investigation deals the thermal stability of the Nickel chelates of 3 -(phenyl) -1 -( 2'hydroxynaphthyl ) -2 -propen -1 -one (PHPO) , 3 -( 4 -chlorophenyl ) -1-(2'-hydroxynaphthyl ) -2 -propen -1 -one (CPHPO), 3 -( 4 -methoxyphenyl ) -1 -(2'-hydroxynapthyl ) -2-propen -1-one (MPHPO), 3-(3,4-dimethoxyphenyl)-1-(2'-hydroxynaphthyl)-2-propen-1-one (DMPHPO) and evaluation of kinetic parameters employing the differential Freeman-Carroll equation 20 the integral method using the Coats-Redfern equation 21 and the approximation method using the Horowitz-Metzger equation. 22…”

Structure and thermal characterization of tris-thallium(III) glycollate

“…The work on the thermal decomposition of metal complexes of hydroxy acids is very limited. As an extension of our previous studies [4][5][6][7][8][9], the present report deals with the thermal decarboxylation of TI(III) glycollate, with a view to understanding the mechanism of the decomposition and the nature of the decomposition products. The characterization ofTl(IlI) glycollate was carried out through elemental analysis, IR spectra, TG, DTG and DTA studies.…”

“…However, work on the thermal decomposition of heavy metal carboxylates started only a short time ago [3]. Recently, we reported on the thermal dehydration and decomposition of metal complexes of salicylic and nuclear substituted salicylic acids [4][5][6][7][8][9]. The work on the thermal decomposition of metal complexes of hydroxy acids is very limited.…”
