Dycosthren Khaki GG Reduction Green 8 Uses and Synthesis Methods
Use for cotton fiber and polyester / cotton blended fabric dyeing
Use to restore khaki 2G for cotton, silk dyeing, leveling and affinity are good, is the main dye dyed green. Also used for viscose cotton, polyester-cotton blended fabric dyeing.
Production methods 1,4,5,8-tetrachloroanthraquinone and 1-amino anthraquinone as raw materials, the first two in the presence of copper powder condensation, and then in the presence of aluminum chloride closed loop, after oxidation product. Washed, filtered, dried, crushed to the finished product. The
In the drum reactor, 60 kg of tetrachloroanthraquinone, 150 kg of 1-aminoanthraquinone, 60 kg of sodium carbonate (98%) and 3.5 kg of copper powder (industrial product) were added, and the temperature was raised slowly to 220-230 ℃, insulation 2h. Stop heating, cooling, the material crushed 5h.
Add the water in the reactor 2000L, add the above materials, boiled at 95-100 ℃ for 1h, filtered, washed and dried.
50kg of the above condensed material, 125kg of aluminum trichloride (98%), 25kg of salt powder (industrial) mixed for 30min, and then into a closed-loop pot, slowly warming to 80-90 ℃, stop stirring, let the foam, The temperature is raised to 130-140 ℃, slowly stirring, the temperature rose to 170-180 ℃, keep 30min, add 1200L water has been added to the dilution pot, boiled at 100 ℃ for 30min, filter, washed.
Add 1000 L of water to the oxidation pot, 275 kg of sulfuric acid (98%) and two batches of closed-loop material (about 600-800 L of water) and then add 180 L of sodium dichromate solution (50%, about 90 kg dry product) -102 ℃, insulation 3h. At any time with potassium iodide test paper detection, if the lack of oxidants, each can add 20-30L sodium dichromate solution. After completion of the reaction, the mixture was filtered at 80 ° C, washed with water until neutral, ground and dried.
