Abstract  

The non-isothermal decomposition of anhydrous disilver malonate was studied up to 300°C by means of TG, DTA and DSC techniques in different atmospheres (e.g. N2, H2 and air). Acetic acid, CO2, acetone and CO were identified as the volatile decomposition products using gas chromatography. Silver metal, on the other hand, was identified as the final solid product using X-ray powder diffraction. The mechanism described involves the breakdown of adsorbed radicals, probably including-CH2COO- and related species, on the surface of the metallic silver product. The activation energy (ΔE) and the frequency factor (InA) were calculated for the decomposition process from the variation of peak temperature (of the DTA curves) with the rate of heating (φ). The enthalpy change (ΔH), the heat capacity (Cp) and entropy change (ΔS) were calculated from the DSC measurements.
