| description | The utility model belongs to the field of organic chemical intermediate product preparation, and provides a reaction system for preparing paraaminophenol in a kettle type continuous hydrogenation mode. The reaction system comprises a plurality of hydrogenation stills, and overflowing pipes for conveying an alcoholic solution of paraaminophenol and balance pipes for transmitting hydrogen are connected among the hydrogenation stills. The reaction system is high in production efficiency, high in product quality, low in labor intensity of operators, small in equipment investment and low in comprehensive cost. |
