Acid Red 1

Application Features

Soluble in water solution for big red, slightly soluble in ethanol and soluble fiber element, insoluble in other organic solvents. Meet strong sulfuric acid is blue light red, it will be diluted in a yellow after red; Meet nitric acid solution is orange turn orange; Meet strong hydrochloric acid generation red precipitation, dilute it dissolve. The aqueous solution of dyes and strong hydrochloric acid is product red; Add sodium hydroxide is orange brown. Copper ions in dyeing and dark blue colour and lustre to take; Iron ion in color with blue and light. Good levelness. 

Appearance is red powder. Soluble in water, large red in aqueous solution. Slightly soluble in ethanol and cellosolve, insoluble in other organic solvents. When concentrated sulfuric acid is blue-red, it will be diluted to a yellowish red color; Concentrated nitric acid turns orange when it is orange-red solution; it forms a red precipitate when concentrated hydrochloric acid, and dissolves after dilution. In its aqueous solution, concentrated hydrochloric acid is magenta, and sodium hydroxide is orange-brown.
