CAS：12218-96-1| Acid Black 107

Introduction and application of CAS：12218-96-1| Acid Black 107

Purpose Neutral black BGL is mainly used for dyeing wool and silk in weakly acidic or neutral dye baths, dyeing nylon and vinylon in neutral dye baths, and direct printing of wool, silk, and nylon fabrics. When used to dye wool and other fibers in the same bath, nylon will get a slightly darker color, silk will get a slightly lighter color, and diacetate fiber and viscose fiber will be slightly stained. Can also be used for leather dyeing. Used for dyeing silk, wool, tussah silk, nylon, vinylon and blended fabrics such as vinyl/cotton, wool/viscose etc.

Specification of CAS：12218-96-1| Acid Black 107

The production method uses 5-nitro-2-aminophenol, 4-nitro-2-aminophenol, 1-acetamido-7-naphthol, 2-naphthol and acidic medium black A (C.I.mordantBlack1) as raw materials. First, Diazotize 5-nitro-2-aminophenol and 4-nitro-2-aminophenol, and then couple with 1-acetamido-7-naphthol and 2-naphthol respectively, and then together with acid medium black A After complexing with sodium chromium salicylate, filtering and drying, the finished product is obtained. Diazotization. . Coincidence. . complex. . Add 300mL water and 31mL hydrochloric acid (30%) into the diazotization reaction bottle and stir evenly. Then add 10.2g 5-nitro-2-aminophenol, 5.5g 4-nitro-2-aminophenol and 12mL NaOH solution (40%), stir for 2 hours, then cool to 10-15°C, and start to drop 22mL NaNO2 solution (30%) ), complete the addition within 30 minutes, and continue stirring until the end point to obtain diazo liquid. Add 120mL water and 12mL NaOH solution (40%) to the coupling reaction bottle, stir, raise the temperature to 30-40°C, add 5.4g 2-naphthol and 14.0g 1-acetamido-7-naphthol, stir well, and cool to 10 -15℃, add the above diazo liquid dropwise, and finish the addition within about 1 hour. Continue stirring for 1-2h to the end point to obtain the azo compound. Add sodium chromium salicylate solution and acidic medium A solution to the complexing reaction bottle, stir and raise the temperature to reflux for about 3 hours, cool to 60°C, add the above coupling solution, adjust the pH value to 8-8.5 with NaOH solution, raise the temperature and reflux for 4 hours. Cool the temperature to 60°C, adjust the pH value to 7.5 with hydrochloric acid, add salt to salt out, filter, wash the filter cake with water until neutral, and dry it to obtain the finished product.
