Samaron Blue GS - Uses and synthesis methods
introduction
disperse blue BGL, blue powder, is formed by sulfonation, nitration and reduction of 1,5-dicarboxyl A,8-hydrocyan -2.6-sodium disulfonate from 1,5-shuttle onion, and then in the presence of boric acid and sulfuric acid, it is added with phenol and anisole, transposition and desulphurization. Dispersed blue BGL is used for printing and dyeing polyester and its blended fabrics, and has good color matching performance with yellow brown 2HFL and red jade 2GFL.
production method
Using 1, 5-dihydroxyanthraquinone, phenol, and this methyl ether as raw materials, first sulfonate, nitrate, and reduce 1, 5-dihydroxyanthraquinone to obtain 1, 5-dihydroxy-4, 8-Diaminoanthraquinone -2, 6-disulfonate sodium, and then add it with phenol and anisole respectively, and finally hydrolyze the sulfonic acid group to obtain the product. After filtration, water washing to neutral, grinding, drying to obtain the finished product..
1 part of 1,5-dihydroxyanthraquinone, 13.98 parts of fuming sulfuric acid and 0.53 parts of anhydrous sodium sulfate were sulfonated at 110-115 ℃ for 4 hours and diluted with 6.92 parts of sulfuric acid. The sulfonated dilution is mixed with the prepared mixed acid [prepared from 4.73kg of nitric acid (95%), 9.7kg of sulfuric acid (96%) and 1.9kg of water], heated to 55-60 ℃ for nitrification, cooled and filtered. Take 47.2kg of nitrification filter cake and 8.25kg of sodium sulfide (100%), carry out reduction reaction at 75-78 ℃ for 1.5-2h, press filtration, wash with salt and alkali solution until there is no sodium sulfide, and obtain 1,5-dihydroxy -4,8-diaminoanthraquinone -2,6-disulfonate sodium (I).
take 1 part (I), 1.2 parts anisole, 31 parts sulfuric acid, 2.34 parts boric acid and 82kg of ice water, carry out addition reaction at 12 ℃ 2 ℃ for 1h, dilute with water, translocation at (95±3)℃, and keep warm for 3h. Then add 8.2kg of table salt, filter, and wash with 2% salt water until neutral. Take 1 part of the indexed product filter cake, 34kg of ammonia water (35%) and 0.99 parts of sodium hydrosulfonic acid group hydrolysis reaction at 60-70 ℃, the reaction is finished, filtered, washed with hot water until neutral, and the filter cake is mixed with 2 parts of diffusion agent to obtain A component dye.
synthesize component B dye and replace anisole with 2.55 parts of phenol. The translocation reaction was carried out at 90 ℃ 2 ℃ for 3h. The rest is the same as the synthetic A component. A component dye and B component dye are mixed in a certain proportion to obtain the finished product.
