Problems solved by technology
[0002] With the development of science and society, the country has been promoting the development of science and technology. There has always been a problem in the field of preparation technology of phthalocyanine green. The appearance of phthalocyanine green is yellowish green powder with bright color and strong tinting power. It is insoluble in water, ethanol and organic solvents, and its general preparation method is to use copper phthalocyanine as the matrix and low-temperature eutectic as the flux to carry out chlorination, pickling, alkali washing, drying, pigmentation treatment, drying, crushing and other processing processing, but there are defects such as slow switching of liquid addition and incomplete drying during this process, and the device of this invention solves this problem
