摘　　要：采用一锅法高效制备蒽醌类蓝色聚氨酯单体。在碱性介质中,用保险粉将1,4-二羟基蒽醌还原为隐色体,后者与乙醇胺进行亲核取代,生成含有二个羟乙基的墨绿色中间体,再在通过氧化反应得到一种含蒽醌发色母体结构的可聚合染料单体:1,4-二(羟乙基)氨基蒽醌。该产物在乙醇中的最大可见吸收波长λ_(max1)=591 nm,λ_(max2)=636 nm。用MS、NMR方法表征了目标产物的化学结构,用聚合后的聚氨酯色浆对PU革进行涂抹,发现性能优异,色牢度优良。Blue polyurethane monomer containing anthraquinone group is efficiently prepared by one- pot reaction. 1,4- dihydroxyanthraquinone is reduced by sodium hydrosulfite to obtain anthraquinone- leuco compound,which is reacted with mono- ethanolamine to nucleophilic substitution,to obtain a dark green product concluding two hydroxyethyl groups. And then this compound could be oxidized to prepare a poly meric dye monomer containing anthraquinone structure ： 1,4- bis（（ 2- hydroxyethyl） amino） anthracene-9,10- dione,which is a polymerizable dye and identified by MS,NMR. The maximum absorption wavelength in ethanol solution is 393. 5 nm and 514. 6 nm. When polyurethane paste prepared from it is used to paint PU leather,the performance and color fastness is excellent.
