生产方法
由4,4'-二(二乙氨基)二苯甲酮(即四乙基米氏酮)在三氯氧磷作用下,与N-乙基甲萘胺缩合,然后水解、提纯、盐析即得成品。原料消耗(kg/t)四乙基米氏酮(100%) 660N-乙基甲萘胺(100%) 360氯仿 200三氯氧磷 400二甲苯 150氢氧化钠(100%) 220精盐 1170以四乙基米氏酮 [benzophenone, 4, 4'-bis (diethylamino)] 和 N-乙基-1-萘胺为原料,将两者在三氯氧磷存在下缩合,经稀释、水解、提纯、盐析即得成品。。
用途
碱性艳蓝 BO 可用于染羊毛、蚕丝和单宁媒染棉纤维,但色牢度均很差。染丝绸时,若用直接耐晒翠蓝 GB 或直接湖蓝 5B 染色后,再用碱性艳蓝 BO 套色,则所得色泽艳丽,为其他染料所不及。本品多用于纸张、竹、木制品着色以及制造蓝墨水、色淀、生物及细菌组织着色。用于圆珠笔油、复写纸、蜡光纸的制造。也可用于竹,木着色及制造色淀。还可用于棉、腈纶、丝绸的染色。
