FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing ammonium bisulphate and can be used in chemical engineering of inorganic substances. The method involves continuously feeding ammonium sulphate into molten ammonium bisulphate in which ammonium sulphate melts and thermally decomposes at temperature of 230-360°C. The obtained ammonia and ammonium bisulphate are continuously removed from the furnace space.
EFFECT: high efficiency of the process and low power consumption.
