Abstract:In the course of the basic research on the ammonia-evaporation reaction of manganese monoxide (MnO), hydroxyl manganese chloride (Mn2(OH)3Cl) was found. The solubility and phase diagrams of the hydroxyl manganese chloride were investigated. The aqueous thermostat and vibrating bed were used to determine the solubility of hydroxyl manganese chloride in water, ammonium chloride and manganese chloride system, and the phase diagrams of multicomponent system were drawn. The research results indicate that hydroxyl manganese chloride has been produced in laboratory and is in favor of the solid-liquid separation at high temperature.
Key words: ammonia-evaporation; hydroxyl manganese chloride; solubility; phase diagram
