Abstract
Results are presented from an experimental investigation of the compos ition of condensed phases formed by heating ammonium sulfate and conde nsing the sublimate. Decomposition of ammonia in the presence of the s ublimation products was also investigated. Within the range 225-300-de grees-C, decomposition proceeds with liberation of ammonia and formati on of a melt [NH4HSO4 65.0, (NH4)2SO4 35.0%]. At 300-600-degrees-C the sublimate consists mainly of NH4HSO4 (90.4-97.8%). Conditions have be en determined for the decomposition of ammonia in the presence of sulf ur compounds (number of stages, temperature, catalyst).
