Nitrattoinitriittisalt

Nitrattoinitriittisalt is a synthetic inorganic compound that has been studied primarily in academic chemistry laboratories. Its formula is NH4NO2·3Na3O4, indicating it consists of a ammonium nitrite ion combined with three sodium orthotitanate units. The compound crystallizes in an orthorhombic lattice and has a melting point near 125 °C. The structure contains discrete tetrahedral TiO4 units coordinated to sodium cations, while the ammonium and nitrite groups occupy interstitial sites. Because of the presence of nitrite, the compound can release nitrogen oxides under thermal or acid conditions, a property that has attracted interest for potential use as a controlled oxidizer, though it remains largely experimental.

Synthetic routes for nitrattoinitriittisalt typically involve the neutralization of a titanium(IV) acetate solution with sodium acetate and subsequent neutralization by aqueous ammonium hydroxide, followed by oxidation of the resulting mixture with sodium nitrite. The product is isolated by slow evaporation at 50 °C. Alternative synthetic methods have explored ion‑exchange techniques where a preformed sodium orthotitanate gel is treated with ammonium nitrite in the presence of a mild acid catalyst.

Safety data indicate that nitrattoinitriittisalt is corrosive to skin and eyes and should be handled with gloves and goggles. The compound’s nitrite component can release toxic nitrogen dioxide gas when decomposed, especially under acidic or high‑temperature conditions. Because of its oxidizing potential it is considered a restricted material in some jurisdictions. Research on the compound has largely been limited to physical characterization, thermal analysis, and evaluation of its decomposition pathways. No large‑scale industrial applications have been reported to date.
