ACID RED 13 Usage And Synthesis
| Chemical Properties | Red to brown powder or granules. Soluble in water. Slightly soluble in ethanol. |
| Uses | Disodium 4-[(2-hydroxy-6-sulfonato-1-naphthyl)diazenyl]-1-naphthalenesulfonate is a monoazo dye with fluorescent properties. It is a ground water pollutant, removed via photodegradation. |
| Definition | ChEBI: C.I. Acid Red 13 is a monoazo compound and a member of naphthalenes. |
| Preparation | 4-Aminonaphthalene-1-sulfonic acid diazo, and 6-Hydroxynaphthalene-2-sulfonic acid coupling. |
| Properties and Applications | red. Soluble in water is cherry red, slightly soluble in ethanol (the pale of the red light purple), almost insoluble in acetone. Strong sulfuric acid in purple, will have its dilution cherry red (produced orange precipitation); Meet nitric acid for yellow light red. Its water solution with hydrochloric acid for yellow orange; Add thick sodium hydroxide solution for orange light brown. Used for wool, silk dyeing, can also be used for the feathers, paper, soap, leather, wood, cosmetics and pharmaceutical color.
