摘　　要：采用直接加热法对某化工厂对苯二酚生产过程中得到的硫酸锰副产品进行了分离纯化的实验室研究，以分离后产品中的二价锰含量作为标准评价纯化效果，研究表明将样品在电炉上加热至无白烟后于马沸炉中恒温，温度在520-620℃时均能达到很好的纯化效果。The by - product manganese sulfate produced in the produce of hydroquinone in a chemical plant was studied by direct heating in lab, after a separation of two products price manganese content as a standard evaluation of purification effect, the study showed the sample electric furnace heated to no white smoke after Ma boiling furnace thermostat, the temperature at 520 - 620℃ were able to achieve very good purification.
