Copper Phthalocyanine

This is Copper Phthalocyanine Blue Crude with chemical group Copper -Phthalocyanine Blue. A process for the production of a copper phthalocyanine by a urea method, which enables the production of a highly pure copper phthalocyanine andor its derivative by a uniform reaction, i.e., is free from problems of an insufficient mixing, nonuniformity in heat transfer and adhesion of the reaction mixture to a reactor wall, the process comprising heating a raw material mixture containing a phthalic acid, a nitrogen source, a copper compound and a catalyst in an inert solvent, the process being carried out in the presence of a surfactant which enables the raw material mixture and a reaction product to be dispersed in the inert solvent while the raw materials are being reacted and which can be removed or deactivated by hydrolysis with an acid or an alkali at a step of purifying the reaction product or forming the reaction product into a pigment after the reaction.
