摘　　要：河南开普化工股份有限公司利用烧碱生产中副产电解氢作为氧源，进行了邻硝冬苯甲醚催化氯化法还原制取邻氮基苯甲醚的扩大试验，在催化剂用量l％、反应温度130℃、反应压力L6MPa的优化工艺条件下．邻氮基苯甲醚的转化率平均在99.3％以上，为进行工业化生产的设备设计、工艺探索提供了有力的保证。Expanded experment for synthesis of o - aminophenolmethyl ether from o - nitrophenolmethyl ether by catalytic hydrogenation using by product electrolysis hydrogen from caustic soda production in our company as hydlogen source are carried out in our company. The optinal conditions are as follows ： the consumption of catalyst 1% , rcaction tomperature.150℃ and reaction pressure 1. 6MPa. The yield of o - aminophcnolmethyl ether is above 99. 3%. The experiment provides a strong basis for the equipment design of industrial unit or the exploration of process technology.
