Physical and Chemical Properties | Dark red-purple powder. Dissolved in water, the aqueous solution was red purple, and the addition of concentrated hydrochloric acid was red; The addition of concentrated sodium hydroxide solution was blue. Soluble in ethanol red purple. Soluble in ethylene glycol ether, acetone-soluble and benzene, insoluble in other organic solvents. In concentrated sulfuric acid was orange-brown, diluted purple; In concentrated nitric acid red solution, then turned brown. When dyeing, the color light of copper ion and iron ion was slightly dark, and the color light of chromium ion was slightly changed. |

Use | acid Violet 2R can be used for dyeing wool, silk, nylon and direct printing of wool and nylon fabrics, also used for leather, paper coloring. It can be combined with an acidic green VS (C.I.Acid Greenlt) to form an acidic cyan GGR. for wool dyeing |
production method | with 2-amino-5-nitrobenzenesulfonic acid and gamma acid (1-napol-7-amino-3-sulfonic acid) as raw materials, the product is obtained by diazotization of 2-amino-5-nitrobenzenesulfonic acid and coupling with gamma acid. After salting out, filtration, drying, grinding to get the finished product.. |
