Disperse Yellow 64 - Reference Information
| Introduction | disperse Yellow SE-3GL chemical name is 2-(4-bromo-3-hydroxy-2-quinolyl) indane-1, 3-dione, trade name for the solvent yellow 176, solvent yellow FS, for the bright yellow powder. Disperse Yellow 54 is dissolved in a certain concentration of sulfuric acid, and bromine is added dropwise at a certain temperature. After adding bromine Dropwise, the temperature is raised to 70-95 ℃, and then the temperature is maintained for 2-6 hours. After the reaction is finished, water is added to dilute the material, after filtration and washing, 2-(4-bromo-3-hydroxy-2-quinolyl) indan-1, 3-dione was obtained, I .e., dispersion yellow SE-3GL. |
| Application | disperse Yellow SE-3GL is mainly used for dyeing polyester, which can obtain bright pure yellow, excellent light fastness and good hiding property, is the main dye, light color dye. As one of the three primary colors, the three primary colors can be composed of disperse red 3B (or disperse red FB) and Disperse Blue 2BLN (or Disperse Blue FBL), and have good compatibility, good levelness and stable color and light. It is also used for direct printing of polyester silk; It is used for dyeing polyester-wool blended products with less wool staining. Can also be used for nylon, acetate fiber dyeing. |
| preparation | A preparation method of disperse Yellow SE-3GL, as follows: add 20g disperse Yellow 54 and 300g sulfolane to a 500ml four-mouth bottle, stir and dissolve for 30 minutes, adjust the temperature to 50-55 ℃, add 7.86g of bromine Dropwise, control adding within 1 hour, after adding bromine Dropwise, raise the temperature to 75 ℃, keep the temperature for 1 hour, after the end of the heat preservation, the temperature is cooled to 50 ° C. And filtered, and 291.8g of mother liquor is recovered. The filter cake is washed with hot water to obtain 26.84g of product disperse Yellow SE-3GL, with a content of 98.66%, with bright appearance. |
| Use | for dyeing polyester fiber and fabric |
