摘　　要：介绍了4,4′-二氨基二苯醚合成方法的研究进展,阐述了其工艺条件。经过分析比较,认为以对硝基氯苯为原料用改进的一步缩合法合成4,4′-二硝基二苯醚中向体,然后再催化加氢得到4,4′-二氨基二苯醚是较好的合成路线。The developments of synthetic methods of 4,4'-diaminodiphenyl ether(DADPE)and its re- action conditions were reviewed.Based on comparison,we suggest that with the improved one step condensation method for producing intermediate 4,4'-dinitrodiphenyl ether(DNDPE)from the raw material p-chloro-nitrobenzene,and then through catalytic hydrogenation for producing DADPE are the better synthetic routes.
