Abstract

Thermogravimetry and infrared spectroscopy were used to study the reactions within solid NaN3/zeolite mixtures. H-form zeolites were converted to Na,H-form already at room temperature, while hydrazoic acid (HN3) was evolved. Hydrazoic acid and NaOH was formed in the reaction with H2O, bound to any of the cationic zeolite forms. In absence of mass transport limitations the rate of mentioned reactions was shown to depend on the protonic acidity of the zeolite, i.e., on the zeolite structure and composition. The NaN3, not consumed in mentioned reactions decomposed to metallic sodium and nitrogen at about 400-460 °C.
