Abstract

Contact of adsorbed ammonium nitrite, NH₄NO₂, with HCl vapor or a solid acid such as the zeolite HY, significantly lowers the temperature of its decomposition to N₂+H₂O. Protonated NH₄NO₂ decomposes at room temperature. The decomposition of ammonium nitrite is one of the steps in the catalytic reduction of NO _x with ammonia or other reductants.
