Abstract

The invention relates to a copper phthalocyanine refining device and method. The device comprises a reaction unit, a separation unit and a post-treatment unit. The reaction unit comprises a reaction device with a heating function; the separation unit comprises a filtering device and a washing device; the reaction device, the filtering device and the washing device are connected in sequence; the post-treatment unit comprises a distillation device and a heat preservation filtering device; the discharge ports of the distillation device comprise a top discharge port and a bottom discharge port, the filtering device and the washing device of the separation unit are both connected with the distillation device, the top discharge port of the distillation device is connected with the reaction device, and the bottom discharge port of the distillation device is connected with the heat preservation filteing device. According to the method, cyclic utilization of the solvent can be achieved, the wastewater amount is greatly reduced, and organic matter in the wastewater is separated and the wastewater treatment difficulty is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of pigment production, mainly to the technical field of production and refining of copper phthalocyanine, and in particular to a copper phthalocyanine refining device and method. Background technique [0002] Phthalocyanine blue pigment has a history of nearly 90 years since it was industrialized in the 1930s. Phthalocyanine blue and its halogen derivatives have bright color, strong tinting power, and excellent weather resistance. They are widely used in the fields of plastics, inks, paints, inks, fibers, powder coatings, etc., and occupy a very important position in organic pigments. . Phthalocyanine blue pigment is obtained by refining and purifying crude copper phthalocyanine, grinding, acid-base treatment and other pigmentation processes. Copper phthalocyanine production methods include solid-phase method and solvent method. The mainstream process route is the phthalic anhydride-urea process, and the r...
