Abstract:
     The process for preparing sodium nitrate and ammonium chloride is carried out by solid-phase transformation of ammonium nitrate and sodium chloride with equal molal weight in pre-prepared eutectic mother liquid at ambient temp. (0-40 deg.C) and separating. Its advantages include saving energy because of no need of heating and vaporation and cyclic use of eutectic mother liquid.
