Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) was used to follow the decomposition kinetics of ethylene glycol dinitrate (EGDN) adsorbed on a zinc oxide surface at 313 K. The principal decomposition products are most likely a variety of carbonyl, carboxylate, and carbonate species. The appearance of these products follows zeroth-order Langmuir kinetics. Another decomposition product, carbon monoxide, exhibited more complex kinetics. Overall, because of its reactivity with EGDN, ZnO does not appear to be a suitable material for an explosive preconcentrator device.
