Mechanism of Room-temperature Solid State Reaction of Hexamethylene Tetramine with Cobaltous Chloride

The cold-melting mechanism and the cold-dissolving-melting mechanism were further studied by TG/DSC and in situ micro-photographs techniques with the mixture of hexamethylene tetramine and CoCl₂·6H₂O as the sample for the model reaction. The method of UV-Visible Diffuse Reflectance spectroscopy was theoretically and experimentally proposed to investigate the initial kinetic characters of the solid state reaction with the mixture of the above mentioned model reaction sample. The results indicate that the reactive rates are varied non-linearly with the change of reaction time. The fastest reaction rate can be reasonably explained by the formation of the cold-melting layer or cold-dissolving-melting layer.
