Uses
Acid Red 35 is an organic azo dye used in edible food packaging, hair dye, and inkjet inks.
Preparation
O-Methylaniline diazo, and 4-Aminonaphthalene-1-sulfonic acid coupling.
Properties and Applications
colourful red blue light. Dark red powder. Soluble in water, soluble in ethanol in a certain extent a product red, slightly soluble in acetone. A product of sulfuric acid in red, pink is diluted. Its water solution and strong hydrochloric acid, a product red, add sodium hydroxide solution is orange brown. In dyeing copper and iron ion colour and lustre is a little blue. Mainly used for wool fabric dyeing and printing, with chromium after mordant dyeing color unchanged. But in the silk, wool products direct printing, and can also be used for the paper, leather color, also used in the manufacture of sediment and ink color.
