ACID RED 151 Usage And Synthesis
Chemical Properties
Dark red powder. Still soluble in water, aqueous solution is turbid brown-orange, adding concentrated hydrochloric acid is orange-brown; adding concentrated sodium hydroxide solution is dark purple. Soluble in ethanol is orange-red, also soluble in ethylene glycol ethyl ether, insoluble in other organic solvents. In concentrated sulfuric acid is bluish green, diluted weak brown-orange color.
Uses
C.I. Acid red 151 is an acid red dye that can be adsorbed and removed by bentone clay.
Preparation
4-((4-Aminophenyl)diazenyl)benzenesulfonic acid diazo, and Naphthalen-2-ol coupling.
Flammability and Explosibility
Not classified
Properties and Applications
red. Dark red powder. Soluble in water is cloudy brown light orange, soluble in ethanol (orange) and soluble fiber element, insoluble in other organic solvents. Meet strong sulfuric acid as blue light green, a weak light brown after diluted orange. Its water solution and strong hydrochloric acid for orange brown; Add thick sodium hydroxide solution for dark purple. Apply to polyamide, silk, wool and wool fabric dyeing of, also can used for the polyamide plastic shading. Can also be used in leather dyeing.
