1. Use copper phthalocyanine as raw material, sulfonate it with fuming sulfuric acid, and then neutralize it with diphenylguanidine to obtain the product. The finished product is filtered and dried.
2. Using copper phthalocyanine blue as raw material, sulfonate and neutralize with fuming sulfuric acid to obtain the product. The finished product is salted out, filtered, dried and crushed..
150g of fuming sulfuric acid with a concentration of 104.5% was added to the reaction bottle, the temperature was raised to 50 ℃ and maintained, 25g of copper phthalocyanine was slowly added under stirring, stirring was continued for 2h after adding, and then the temperature was raised to 65 ℃ for 10h to the end of sulfonation reaction. Cooling to below 40 ℃, pour the material into the ice water and settle, pour out the upper layer of clear water, filter the slurry, beat the filter cake with water, and add sodium carbonate aqueous solution until the pH value reaches 7-7.2 as the end point. Then dry and grind the finished product.
