摘要
介绍了3,4’—二氨基二苯醚合成方法的研究进展,阐述了其工艺路线及条件。分析比较认为,以对硝基氯苯和间氨基苯酚缩合法合成3-氨基-4’-硝基二苯醚中间体,再催化加氢制得3,4’—二氨基二苯醚是较好的合成路线。
The developments of synthetic methods of 3,4′-diaminodiphenyl ether（DADPE） and its Process and reaction conditions were introduced. Based on comparison, we suggested that condensation method for producing intermediate 3-amino-4′-nitro-diphenyl ether （ANDPE） from the raw material m-Aminophenol and p-chloro-nitrobenzene, and then through catalytic hydrogenation for producing DADPE is the better synthetic route.
