| | CI 50325 Usage And Synthesis |
| Preparation | 6,8-Bis(phenylamino)naphthalene-1-sulfonic acidand 2,5-Diamino-4-methoxybenzenesulfonic acid condensation, and then product (add) ammonia in the cuprous oxide catalyst for the air oxidation. | | Synthesis |
Wool Fast Violet B 21, C.I. 50 325 [6837-46- 3], from 1,3-bis(phenylamino)naphthalene-8- sulfonic acid and 2-methoxy-1,4-phenylenediamine- 5-sulfonic acid proceeds differently. In the cyclization step the methoxyl group is split off as methanol. Therefore, the dye can also be synthesized from 1,4-phenylenediamine-2-sulfonic acid.
| | Properties and Applications | blue purple. Soluble in water and ethanol for red light purple. The strong sulfuric acid for green, purple for red after diluted. In water solution is a deep red to join sodium hydroxide, and precipitation.
