摘要: This invention relates to improved catalytic process for the manufacture of copper phthalocyanine by allowing phthalic anhydride to react with urea and a copper compound, in the presence of a hydrophobic liquid (dispersing agent), characterized by the presence, along with the catalyst and the dispersing agent, of a promoter selected from particular classes of amides, imides, ureas, thioureas, guanidines, amines or sulphoxides.
