摘要
研究以溴氨酸与４，４′－二氨基二苯甲烷缩合反应合成弱酸性蓝Ｇ，收率９０％．将其磺化改善水溶性，合成弱酸性蓝ＮＧＳ，收率８５％以上，并对比了合成染料与商品染料维亚龙坚牢蓝ＦＦＧ的染色性能．
his paper describes the preparation of Milling Dyes BIne G by using condensation of bromamine acid with 4,4' -bis-aminophenylmethane, with its yield being 90%. The Milling Dyes Blue NGS has been synthesized by sulfonating Blue G and its solubility has been improved (yield 85% ). The byeing properties of synthsized dyes have been compared with those of commercial dyes Vialon Fast Blue FFG.
