Using 1, 4, 5, 8-tetrachloroanthraquinone and 1-aminoanthraquinone as raw materials, the two are first condensed in the presence of copper powder, then the ring is closed in the presence of aluminum trichloride, and the product is obtained after oxidation. After washing, filtering, drying and crushing, the finished product is obtained. Add 60kg of tetrachloroanthraquinone, 150kg of 1-aminoanthraquinone, 60kg of sodium carbonate (98%), 3.5kg of copper powder (industrial product) into the drum reactor, and slowly increase the temperature to 220-230 within 3-4h ℃, keep for 2h. Stop heating and cooling, and crush the material for 5h. Add 2000L of water to the reaction kettle, add the above-mentioned materials, boil at 95-100℃ for 1h, filter, wash and dry. Mix 50kg of the above condensed material, 125kg of aluminum trichloride (98%), 25kg of fine salt powder (industrial product) for 30min, then put it in a closed-loop pot, slowly raise the temperature to 80-90℃, stop stirring, let it foam, Warm up to 130-140℃, stir slowly, temperature rise to 170-180℃, hold for 30min, put it into a dilution pot with 1200L water, boil at 100℃ for 30min, filter and wash with water. Add 1000L of water, 275kg of sulfuric acid (98%) and two batches of closed-loop materials (about 600-800L for beating with water) in the oxidation pot, then add 180L of sodium dichromate solution (50%, dry weight about 90kg), and heat to 100 -102℃, keep for 3h. Use potassium iodide test paper to test at any time. If the oxidant is insufficient, add 20-30L sodium dichromate solution each time. After the reaction is over, press filter at 80°C, wash with water to neutrality, grind and dry to obtain a finished product.
Reduced Khaki 2G is used for dyeing cotton and silk. It has good levelness and affinity, and is the main dye for dyeing grass green. It is also used for dyeing viscose and polyester-cotton blended fabrics.
