性质描述:

黑褐色粉状。溶于水，并呈枣红至桨红色；稍溶于醇，并呈棕光品红色；微溶于丙酮。在浓硫酸中呈暗蓝色，稀释后呈浅红棕色；在浓硝酸中呈枯桔黄色。其水溶液，加浓盐酸无大变化；加氢氧化钠浓溶液转棕光品红色。水中溶解度（90℃）为25g/L。染色时遇铜、铁，色光影响较大。

生产方法:

由6-硝基-1，2，4-酸氧体（即6-硝基-2-羟基-1-重氮萘-4-磺酸）与1-萘酚进行偶合，，经盐析，过滤，干燥等片理过程，制得该品。产品外风为黑褐色均匀粉末，色光与标准品近似（蓝光灰→蓝光黑），强度为标准品100±3（分），水分含量≤5%，水不溶性杂质含量≤1%，细度（通过80目筛余物含量）≤5%，在羊毛上的染色坚牢度符合标准品（日晒牢度7级，皂洗、水浸、汗渍、煮呢等褐色牢度及碳化、熨烫、干洗等牢度均为4-5级，干摩擦牢度3-4级）。原料消耗（kg/t）6-硝基-1，2，4-酸氧体（100%） 500甲萘酚（100%） 255烧碱（100%） 255纯碱（工业） 215盐酸（31%） 675精盐 450

产品说明

一般描述

Eriochrome^® Black T可用作络合滴定的指示剂。它起酸碱指示剂的作用。Eriochrome^® Black T能与Ca²⁺和Mg²⁺形成复合物，但它与Mg²⁺ 离子的结合能力更强。
铬^® 黑T是羟基-偶氮染料，通常以一钠盐的形式提供。该染料以泛绿色金属光泽的深紫色粉末形式存在。铬黑T可溶于水和乙醇，但不溶于常见有机溶剂。主要作为指示剂，用于乙二胺四乙酸(EDTA)法测定水硬度。

应用

通过络合滴定法，Eriochrome^® Black T已被用于确定Ca²⁺ 的浓度。
