| application | dispersed yellow M-FL is used for dyeing polyester yarn-dyed yarn and polyester knitted fabric. it has excellent dyeing performance, good fastness, can dye monochromatic color, can also form three primary colors with dispersed ruby SE-GFL and dispersed blue 2BLN, and can also be matched with dispersed red RR and dispersed yellow SE-2GL. It is also used for direct printing of polyester fabric and polyester-cotton (viscose) blended fabric, and does not stain cotton and viscose fibers. It can also be used for dyeing diacetate fiber and triacetate fiber, with good dyeing depth. It can only get light color for dyeing acrylic fiber and polypropylene fiber. for dyeing polyester and its blended fabrics |
| production method | using o-nitrochlorobenzene, aniline and chlorosulfonic acid as the main raw materials, o-nitrochlorobenzene and chlorosulfonic acid are first subjected to chlorosulfonation reaction, then condensed with aniline, filtered, ground and dried to obtain the finished product.. 349.5g of chlorosulfonic acid (100%) was heated to 60 ℃, added to the melted 78.8g of o-nitrochlorobenzene (100%), then heated to 105-110 ℃ for 6h, then the product was quickly poured into 1500mL of water (water temperature 0-5 ℃), stirred below 25 ℃ for 30min, filtered, washed with cold water to be neutral, and 160-162g of paste product with 30% water content was obtained. 215mL of water, 14.85g (100%) of light calcium carbonate and 32.1g (100%) of aniline were added into the reactor, stirred and heated to 35-40 ℃, 38.4g of the paste product was added, the temperature was continued to 100 ℃, and the reflux was 8h. Cool to 40°C, filter, and wash with hot water until aniline-free. The product was dried at 100 ℃ to obtain about 53g. |
