reaction equation
Operation process
Condensation Add trichlorobenzene 2776kg, phthalic anhydride 1200kg and urea 1000kg in the kettle, be warming up to 160 DEG C, be incubated for 2h, add trichlorobenzene, 850kg urea and 230kg cuprous chloride for the sixth time, heat up after adding, and keep for a certain time. 867kg of trichlorobenzene and 13.4kg of ammonium molybdate were added for the third time, and the temperature was gradually raised to about 200° C. after the addition, and a heat preservation reaction was carried out. Then move it into a still and add liquid caustic soda, and distill out the solvent with direct steam. Rinse with water, continue to steam, and dry the material with a thin film dryer to obtain 1250kg of crude phthalocyanine blue.
Refining Add 135kg of refined product to 850kg of 98% sulfuric acid to dissolve, keep at 40℃, add 17kg of xylene, heat up to 70℃, gradually cool down to 24℃, dilute in water, stand still for 3h, absorb the upper waste liquid, After repeating this for three times, neutralize with 30% sodium hydroxide to pH=8-9, stir and boil with direct steam for half an hour, wash with water, dry and grind to obtain 118kg of refined phthalocyanine blue.
