yellow-orange fine crystalline powder | [Uses]
Direct Yellow 27 is an organic dye used as a colourant for cellulosic fibers. Dyes and metabolites. | [Preparation]
2-(4-Amino-3-sulfophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acid diazo, and N-(2-methoxyphenyl)-3-oxobutanamide coupling. | [Properties and Applications]
colourful green light yellow. Yellow powder. Soluble in water for lemon yellow, also soluble in soluble fiber element, soluble in ethanol, slightly soluble in benzene and carbon tetrachloride for orange, insoluble in other organic solvents. The strong sulfuric acid dyes for golden brown, diluted becomes shallow; In nitric acid solution for colourful yellow; In strong hydrochloric acid partly dissolved for the golden light orange. The dye solution to join strong hydrochloric acid has golden precipitation; Add thick sodium hydroxide solution with gold orange precipitation. Water-soluble is poorer. Copper ions in dyeing color shade basic unchanged, encounter iron ion colored light tiny have change (4 ~ 5 level), classification of A class SDC. Cotton and viscose neutral white are level 2, white alkaline are 4 levels. Used for cotton and glue dyeing and printing. Can also be used for silk, wool, polyamide fiber and its blended fabric dyeing, also used in leather and pulp color.
