uses | weak acid purple BB is mainly used for dyeing wool, silk, nylon fabric, also used for leather, paper, plastic coloring. |
production method | with 4,4 '-diamino-3, 3'-dimethyldiphenylcyclohexane and 4, 6-dihydroxy-2-naphthalenesulfonic acid is used as a raw material, and the former is first double nitrided, and then coupled with the latter to obtain a product. The final product was obtained by filtration, drying and pulverization.. 7340G of 4,4 '-diamino-3, 3'-dimethyldiphenylcyclohexane hydrochloride solution (3%) and 304.2G of hydrochloric acid (30%) were added to the diazotization tank, and the temperature was lowered to 0-5 ℃, then 40% sodium nitrite solution (98% NaNO2 142.9G) was slowly added and stirred for 1H. Potassium iodide test paper blue as the end point, temperature 5-10 ℃. Another 100% g of 4, 6-dihydroxy-2-naphthalenesulfonic acid (), 3L of water, and 235g of sodium bicarbonate (industrial product) were stirred until completely dissolved. The temperature was lowered to 5 ° C., and the above diazo solution was slowly added to maintain a pH of 7-7.5 and a temperature of 10-15 ° C., and stirred for 1H until the diazonium salt disappeared. About 110g of sodium carbonate (industrial) was then added, the pH was adjusted to 9, and the temperature was maintained at 10-15 °c for 3 hours. After filtration and drying, about 1600g of dye was obtained. |
