摘　　要：探讨了硝基苯催化氢化法生产对氨基苯酚的工艺条件,该工艺生产成本比传统工艺低,产品含铁量低,对氨基苯酚含量≥98％,工业污染小。The manufacturing technology condition for para - aminophenol with the method of catalytic hydrogenation by nitrobenzene is studied in thispaper. The manufacturing expenditure of this techno logy is lower than classical one. The ferriferous content of the product is low, the content of paraamino phenol in the product≥98% and the industrialpollution is small.
