Use | Reactive blue KE-GN is mainly used for dyeing and printing of cotton and viscose fabrics, and can also be used for polyester cotton, one-bath dyeing of polyester-viscose blended fabric is brilliant blue. High temperature stability is excellent. |
production method | 2-chloro-5-nitrobenzenesulfonic acid, ethylenediamine, tetrachlorobenzoquinone, cyanuric chloride and M-aminobenzenesulfonic acid as raw materials. First, 2-chloro-5-nitrobenzenesulfonic acid is condensed with ethylenediamine, and then its nitro group is reduced. It is then condensed with tetrachlorobenzoquinone to give the [oroxazine] Intermediate. The product is condensed with cyanuric chloride and finally with M-aminobenzenesulfonic acid. After salting out, filtration, drying to obtain the finished product.. |
