Molecular Formula | C37H23ClN10O22S7.6Na |
Molar Mass | 1460.91 |
Physical and Chemical Properties | Dark blue powder. Easily soluble in water, the solubility in water is 80g/L (50 ℃). |
Use | reactive deep blue M-BE is used for dyeing cotton and viscose fiber, which is suitable for exhaustion dyeing and rolling dyeing. High temperature stability is good. Also used for polyester-cotton, polyester-viscose blended fabric, and hemp and silk dyeing. The dyeing fastness was excellent. |
production method | with amino C acid, H acid, 2, 4-diaminobenzenesulfonic acid, M (β-sulfate ethyl sulfone) aniline and cyanuric chloride as raw materials. First, 2, 4-diaminobenzenesulfonic acid is condensed with cyanuric chloride for the first time, then diazotized and coupled with H acid, and then aminoc acid is diazotized and coupled with H acid for the second time, finally, a second condensation of M (β-sulfate ethyl sulfone) aniline was carried out to give the product. After salting out, filtration, drying to obtain the finished product.. |
