• Non-isothermal studies of some adduct molecules of metallic halides with ethylene glycol dimethyl ether of the type MX<SUB>2</SUB>(EGDME)<I><SUB>y</SUB></I> in solid state were carried out with a derivatograph, where M=Mn(II), Co(II), Ni(II), Cu(II) or Cd(II), X=Cl<SUP>−</SUP> or Br<SUP>−</SUP>, EGDME=ethylene glycol dimethyl ether and <I>y</I>=0.5–1. These adduct molecules lost ethylene glycol dimethyl ether in single or multiple steps upon heating. Thermally stable intermediate products were isolated and characterised by elemental analysis and IR spectral measurement. The activation energy for each step of decomposition of the adduct was evaluated from the analysis of TG, DTG and DTA curves of the respective derivatograms. Enthalpy change was evaluated from the DTA peak area and the order of reaction was found to be unity for each step of decomposition. Thermal parameters for the above adducts were compared with those for the corresponding type of adducts with oxo-compounds like dioxane or tetrahydrofuran.
