Application Disperse Blue 359 dry powder 359 Blue belongs to anthraquinone dye, name: 1-amino -4-(ethylamino) anthraquinone -2-carbonitrile. Disperse Blue 359 dry powder 359 blue is widely used, mainly for spray painting, transfer printing, can change the traditional printing and dyeing process, to meet the printing quality and improve the original printing and dyeing pollution of the environmental problems.
preparation I. Aminolysis reaction: bromamic acid (1-amino -4-bromo-anthraquinone -2-sulfonic acid) 1-amino -4-(ethylamino) anthraquinone -2-sulfonic acid was prepared by the alkylation of 1-amino -4-(ethylamino) anthraquinone -2-sulfonic acid. Batch 1: 24g of bromamine, 3g of soda ash were added in a A- 1 ml autoclave, 0.15g of cupric acetate monohydrate, 70% g of water and 15g of 0.5 ethylamine solution were stirred at room temperature for 20 minutes, then slowly heated to 95~98 ℃, and the internal pressure was 0.6 ~ MPa. After 5 hours of heat preservation, the reactants were taken out by cooling, solid-liquid separation to obtain solid amine wet weight 14.4g,HPLC purity of 97.76%; Ammonia solution mother liquor 193.2g, of which amine HPLC purity of 91.17%, 90g ammonia solution was separated and applied to the next batch, the ethylamine in the remaining mother liquor distilled off at 90 °c was added to 90g fresh water for the next batch. II. Cyanation reaction and fractional washing: cyanation of 1-amino -4-(ethylamino) anthraquinone -2-sulfonic acid and fractional washing of filter cake the batch of B- 1:1000ml flask was put into 350g fresh water, 10g of sodium cyanide was stirred for 20min, then A- 1 batches of solid amine and the remaining A- 1 batches of mother liquor were dissolved by ammonolysis. The temperature was slowly raised to 95~98 ℃, and the mixture was refluxed for 7 hours, the purity of the main peak was 85.34%. The mother liquor was collected by hot Suction filtration, and then washed with 6000ml of hot water at 90 °c until neutral. The product was dried to 12.73g, yield 78.05%.
