Ammonium Chloride Separated into Ammonia and Hydrogen Chloride, with the Aid of Metal Oxides

David Ashboren

Open publisher page 3 citations

Abstract

Abstract The two‐stage decomposition of ammonium chloride into ammonia and hydrogen chloride, with the aid of metal oxides, was investigated. Twenty‐one oxides were considered for this sequence, and 14 were actually tested and the temperature range of the reactions determined. The energy requirements for heating the metal chlorides from t1 to t2 were calculated. For Fe2 O3, the temperatures are 200° and 300°, respectively, and the heating requirement ca. 17 × 103 kcal/t NH4Cl converted.
