Abstract

The invention discloses a preparation method of phthalocyanine green G. The preparation method comprises the following steps: adding water into a reactor, adding selected aluminum trichloride into the reactor to carry out reactions, then adding copper phthalocyanine and cuprous chloride into the reactor, mixing, carrying out reactions, then introducing chlorine gas into the reactor, carrying out acid and alkali washing, finally washing the reaction product by a filter press to obtain a semi-finished product, drying, grinding, and filling the powder into bags to obtain finished products. The product is processed by acid and alkali, thus the impurities in the product are few, the physical properties are stable, the fading of the product is also prevented, during the production process, the product is processed by a filter press, the environment pollution is little, the product can be concentrated in the filter press, and thus the waste is reduced.

Description

technical field [0001] The invention belongs to the field of pigment preparation, in particular to a preparation method of phthalocyanine green G. Background technique [0002] Phthalocyanine Green G perchlorinated copper phthalocyanine, with an average of 14 to 15 chlorine atoms per molecule, the shade is blue and green. Phthalocyanine green G, like phthalocyanine blue pigment, has good various application properties, for example, its light resistance, heat resistance, weather resistance and solvent resistance are quite excellent. However, the current preparation process of Phthalocyanine Green G generally involves direct water washing after reacting in a reactor. Such production is particularly likely to pollute the environment, and is easy to waste products, and the quality and effect of the produced products are not high at the same time. Contents of the invention [0003] The purpose of the technical solution of the present invention is to provide a preparation metho...
