ACID VIOLET 48 - Reference Information
| Introduction | acid Violet 48 is an acid dye. Acid Violet 48 is soluble in water, solubility is 80g/L(90 ℃), the aqueous solution is magenta, after adding hydrochloric acid, it is paste red, accompanied by precipitation; After adding sodium hydroxide, the color is better, with the formation of precipitates. In concentrated sulfuric acid was Magenta, diluted to light purple, there is precipitation; In concentrated nitric acid was brown. |
| Use | weak acid Violet N-FBL can be used for dyeing wool, silk, nylon and wool blended fabrics, also used for wool, direct printing of silk fabrics. Used for wool and other fibers in the same bath dyeing, nylon color is similar to wool, silk is shallow, polyester slightly stained, cellulose fiber rarely stained. This product is mainly used for dyeing loose wool, wool, skein yarn and cheese yarn and other wool spinning semi-finished products, the color light is blue, the color quantity is high, the color fastness is good, suitable for dyeing to deep color. Levelness is poor, not sensitive to chromium salts, can be matched with acid medium dye, or used to adjust the color light. suitable for dyeing and printing of silk, wool and nylon |
| production method | with bromamine acid, trimethylaniline and p-tert-octylphenol as raw materials, first, bromine is condensed with S-trimethylaniline for the first time, then with P-tert-octylphenol for the second time, and finally the product is sulfonated with fuming sulfuric acid and neutralized with alkali. The final product was obtained by filtration, drying and pulverization.. |
