| use | cationic red 2GL is used for dyeing acrylic fiber, the color is not bright, it is mainly used for dyeing acrylic loose fiber, fiber strip and acrylic wool, it is also suitable for dyeing wool and viscose nitrile blended fabric, and it rarely stains wool and viscose. It can be used for dyeing diacetate fiber and acid modified polyester and direct printing of acrylic fiber, diacetate fiber and acid modified polyester fabric. It is often composed of three primary colors with cationic light yellow 2GL and cationic brilliant blue RL. The light to medium colors such as rice, coffee, camel and gray are dyed on acrylic wool blankets. It is also used for direct printing of acrylic wool blankets. for dyeing and printing of acrylic and blended fabrics. Staining in acetic acid-sodium acetate bath, pH should be between 4-6. It often forms three primary colors with cationic light yellow 7GL and brilliant blue RL, which are dyed light to medium color on acrylic wool blanket. Mainly used for dyeing acrylic loose fibers, fiber strips and acrylic wool |
| Production method | Using 2-aminothiazole and N-methyl-2-phenylindole as the main raw materials. 2-Aminothiazole is diazotized with sodium nitrite and sulfuric acid, coupled with N-methyl-2-phenylindole, and then methylated with dimethyl sulfate (quaternary amination), and finally filtered, Dry to obtain the finished product. Kg/ton sodium hydroxide (100%) 1400 refined salt 270 aniline 325 2-aminothiazole (100%) 152 hydrochloric acid (31%) 2010 magnesium oxide 100 sodium sulfite 470 emulsifier OP 90 sodium bisulfite 710 anhydrite 50 zinc ingot 12 activated carbon 12 xylene 5 crystalline copper sulfate 1.4 glacial acetic acid 12 phenol 2.5 acetophenone 290 acrylonitrile 134 zinc chloride 590 dimethylformamide 460 dimethyl sulfate 750 phosphorus oxychloride 320 benzene chloride 30 with 2-aminothiazole and N-methyl -2-phenyl indole as the main raw material, first, 2-aminothiazole is diazotized with sodium nitrite and sulfuric acid at -5-4 ℃, then coupled with N-methyl -2-phenyl indole, and finally methylated with dimethyl sulfate, filtered, Wash and dry to obtain the finished product.. Add 408L of water and 330kg of sulfuric acid (93%) to the reaction pot, cool to 3 ℃, add 36kg of 2-aminothiazole (100%), continue to cool to -3-4 ℃, add sodium nitrite solution (containing 30kg of sodium nitrite) dropwise, add it within 1.5-2h, and keep it for 40min. Add 600L of water and 1.5t of ice into another reaction pot, then inhale the above diazotized materials, cool to 0-3 ℃, slowly add the prepared N-methyl -2-phenyl indole solution [prepared by 300L of water, 6kg of emulsifier OP, 69kg N-methyl -2-phenyl indole and 555kg of sulfuric acid (93%)], add it within 40-60min, and react to the end point. Then raise the temperature to 23 ℃ for filtration. Add 75L of water and the above-mentioned dye parent filter cake in the reaction pot, adjust the volume to 420L, add 27kg of magnesium oxide below 26 ℃, add 57kg of dimethyl sulfate below 15 ℃, react at 33-35 ℃ for 3 hours, raise the temperature to 90 ℃, adjust the volume to 2200L, filter at 60 ℃, salt out the filtrate, filter and dry to obtain the finished product. |
