性质描述: 红棕色粉状,不溶于水和乙醇;微溶于二甲苯呈枣红色。遇浓硫酸呈暗棕色并转变成蓝色,稀释后呈蓝色。在碱性保险粉还原液中的隐色体呈微红光黄色,在酸性液中呈浅棕色。属硫靛类还原染料。
生产方法: 由萘用乙酐、三氯化铝进行乙酰化,水解后再用多硫化钠、乙醇进行硫化缩合,经脱硫后过滤、干燥,及商品化处理,而制得产品。原料消耗(kg/t)精萘 615乙酐 600二氯乙烷 690乙醇(95%) 950硫磺 2040烧碱(100%) 2100三氯化铝 1690亚硝酸钠 215扩散剂(100%) 640磷酸氢二钠 102
用途: 用于棉、粘纤、蚕线、羊毛、维纶等纺织物染色和印花。对棉的亲和力较差,故较少用于染色。可适用于直接印花、防染印花和苯胺黑地色防染,也适用于浅色至浅中色拔染印花。该品的印染物经脲醛、氰醛、KMEU、BHES等树脂整理后,色光均稍浅;经2D树脂整理后,色光几乎不变。该品的印染物暴露于日光下,易使纤维产生脆化现象。
