摘　　要：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.在进行氧化亚锰(MnO)蒸氨反应的基础研究过程中,发现羟基氯化锰(Mn2(OH)3Cl)这一物质。对该羟基氯化锰的溶解度和相图等进行系统研究;利用恒温水浴和摇床测定不同温度下羟基氯化锰在水中、氯化铵中及氯化锰等体系中的溶解度,并绘制其在多元体系中的相图。实验制备了该物质,并得出羟基氯化锰有利于蒸氨反应中高温固液分离的结论。
