Embodiment 1
[0034] (1) Add 2,150 kg of aluminum trichloride and 570 kg of sodium chloride into the reaction kettle. When the temperature rises to 145°C, the materials in the kettle begin to melt, and slowly start stirring. After the materials are completely melted, stop heating, and then add 495 kg of copper phthalocyanine and 60 kg of copper chloride;
[0035] (2) After adding copper phthalocyanine and copper chloride, restart the heating to 165°C, keep warm and let chlorine gas react for 18 hours, until no hydrogen chloride is produced in the tail gas detection, stop stirring and stop chlorine flow;
[0036] (3) Put 100kg of the reactants obtained in step (2) into the dilution tank, and start stirring at the same time until the temperature of the material in the dilution tank drops to 70°C, then add the material to a filter press and wash it with water until the washing liquid is neutral. Filtrate A is acidic water containing aluminum salts, and filter cake M is crude phthalocyanine gre...
Embodiment 2
[0041] (1) Add 1710 kg of aluminum trichloride and 570 kg of sodium chloride into the reaction kettle. When the temperature rises to 150 ° C, the materials in the kettle begin to melt, and slowly start stirring. After the materials are completely melted, stop heating, and then add 513 kg of copper phthalocyanine and 57 kg of copper chloride;
[0042] (2) After adding copper phthalocyanine and copper chloride, turn on the heating again to 170°C, keep warm and pass chlorine gas to react for 14 hours, until no hydrogen chloride is produced in the tail gas detection, stop stirring and stop chlorine flow;
[0043] (3) Put 100kg of the reactants obtained in step (2) into the dilution tank, and start stirring at the same time until the temperature of the material in the dilution tank drops to 70°C, then add the material to a filter press and wash it with water until the washing liquid is neutral. Filtrate A is acidic water containing aluminum salts, and filter cake M is crude phthalo...
Embodiment 3
[0048] (1) Add 2,850 kilograms of aluminum trichloride and 456 kilograms of sodium chloride to the reaction kettle. When the temperature rises to 155°C, the materials in the kettle begin to melt, and slowly start stirring. After the materials are completely melted, stop heating, and then add 495 kg of copper phthalocyanine and 86 kg of copper chloride;
[0049] (2) After adding copper phthalocyanine and copper chloride, restart the heating to 168°C, keep warm and let chlorine gas react for 16 hours, until no hydrogen chloride is produced in the tail gas detection, stop stirring and stop chlorine flow;
[0050] (3) Put 100kg of the reactants obtained in step (2) into the dilution tank, and start stirring at the same time until the temperature of the material in the dilution tank drops to 70°C, then add the material to a filter press and wash it with water until the washing liquid is neutral. Filtrate A is acidic water containing aluminum salts, and filter cake M is crude phthal...
