12238-01-6 - Reference Information
| Use | reactive brilliant red K-WG is mainly used for dyeing cotton and viscose fibers and direct printing of fabrics, with bright and bright colors, when printing, the stain of white cloth was severe. In addition to being used for monochrome, it is also associated with active purple K-3R purplish red. It can also be used for direct printing of cotton blended fabric and two-bath dyeing of polyester/cotton blended fabric. It can also be combined with reactive yellow K-4G, reactive brilliant orange K-GN, reactive brilliant red K-2BP and reactive brilliant blue K-GR to dye medium and deep colors. can be used for cotton or viscose fiber dip dyeing, roll dyeing and pad dyeing, can also be used for wool fabric printing |
| production method | with O-aminobenzene sulfonic acid, K acid (1-amino -8-naphthol -4, 6-disulfonic acid) cyanuric chloride, aminobenzenesulfonic acid as raw materials, first of all, the K acid and cyanuric chloride condensation, and then O-aminobenzene sulfonic acid diazotization, and the aforementioned condensation product coupling, and finally the aminobenzenesulfonic acid and coupling product for the second condensation, after salting out, filtration, drying to obtain the finished product.. 0.01513kmol of cyanuric chloride, 0.01575kmol of kacid were condensed for 3H to give (I). 0.015kmol of anthranilic acid, 0.042kmol of hydrochloric acid, and 0.015kmol of sodium nitrite were diazotized to obtain (II). After coupling (I) with (II), the product was condensed with 0.0165kmol of p-aminobenzenesulfonic acid at a temperature of 40 ° C. For 6h, salted out, filtered and dried. |
