C.I. Reactive Blue 198 Specification

The C.I. Reactive Blue 198, with the cas registry number 124448-55-1, has other names as Dycosactive Blue KE-GN. This chemical is a kind of blue powder and is soluble in water with the solubility of 50g/L. And its product categories are including KE reactive dye; reactive dye.

The production method of this chemical is as below: Before the reaction, prepare the material of 2-chloro-5-nitrobenzenesulfonic acid, ethanediamine, tetrachlorobenzenequinone, tripolyylchlorocyano, m-aminobenzenesulfonic acid. Firstly, condense the 2-chloro-5-nitrobenzenesulfonic acid and ethanediamine, and then restore its nitro; Secondly, condense with tetrachlorobenzenequinone to get azine intermediate; Thirdly, let azine intermediate condense with cyanuric chloride and then condense with metanilic acid to get the crude; Finally, go through a list process of salting out, filtering, drying to get the products.

As to its usage, it is widely applied in many ways. It could be used in dyeing and printing of cotton, fibre fabric and also used in one-bath dyeing of T/C，P/C, and blend fabric to get the cobalt blue with good high-temperature stability.
