| Use | disperse dark blue S-3BG is used for dyeing polyester and its blended fabrics and direct printing of polyester fabrics, it is the main high-temperature disperse dye to dye dark blue and navy, with high sublimation fastness and resistance to dry heat setting. It can be combined with disperse Yellow Brown H2RL and disperse Red Jade H2GFL to form the three primary colors, and can be combined to dye various medium and deep colors. It can also be used for dyeing triacetate fiber, not suitable for dyeing diacetate fiber, nylon, acrylic fiber. mainly used for dyeing of polyester and its blends |
| production method | synthesis of diazo component: the diazo component was prepared from 2, 4-dinitroaniline by bromination.. Coupling component synthesis: Method 1: with P-acetamidoanisole as raw material, by nitration, reduction, Hydroxyethyl, esterification.. Method 2: 2, 4-dinitrochlorobenzene as raw material, by alcoholysis, reduction, Hydroxyethyl, reduction, esterification, acylation.. Dye synthesis: diazotization of the diazo component, coupled with the coupling component to obtain the product. The product was obtained by filtration, grinding and drying.. After stirring and dissolving 160kg of p-acetamidoanisole and 98% of 24kg sulfuric acid in the nitrifying pot, mixed acid (prepared from 98% of 84kg sulfuric acid and 54% of nitric acid) is added and nitration reaction is carried out below 5 ℃, reaction for 8-10H yielded 29kg 2-nitro-4-acetamidoanisole (I). 42kg (I), of water, 7kg of industrial hydrochloric acid and 45kg of iron powder were added to the reducing pan, and the reaction was carried out at 90-100 ° C. For 2H, and the reduced product (II) was filtered to give 27kg. (II) 10kg (calculated as 100%) and 10kg of water were added to the reaction Pan, stirred and dissolved, and the temperature was raised to 80-100 ° C., 4.8 of ethylene oxide was added, and the reaction was carried out for 2H, followed by dehydration to obtain the hydroxyethylated product. Then, 3 times the amount of acetic anhydride of Hydroxyethyl product (100%) was added, and the temperature was raised to 105-110 ° C., and the reaction was carried out for 3H to obtain the esterification product (I. E., coupling component). (III). 195kg of water, 19kg of bromine, 290kg of 2, 4-dinitroaniline and 0.6 of chlorobenzene were added to the reaction pot, and the bromination reaction was carried out at 50-55 ° C. To the end point. 2, 4-dinitro-6-bromoaniline (I. E., The diazo component) is obtained (IV). Dye synthesis, first with 42.3kg 98% sulfuric acid, 4.7kg of sodium nitrite, in 70-80 deg C dissolved, made nitroxyl sulfuric acid. (IV) 17.4, 30kg of acetic acid and the finished nitrosyl sulfuric acid were diazotized and then coupled with (III) 100% (), of acetic acid and of water to give the product. The final product was obtained by filtration, grinding and drying. |
