  • Process for producing highly chlorinated copper phthalocyanine
    Patent number: 4218376
    Abstract: Highly chlorinated copper phthalocyanine is produced by charging chlorine under an elevated pressure of 1 to 20 Kg/cm.sup.2 (gauge) into a solution of a copper phthalocyanine in the presence of pyrosulfuryl chloride and a catalyst of sulfur or sulfur chloride.Pyrosulfuryl chloride can be formed by a reaction of chlorosulfonic acid with chlorine and sulfur or sulfur chloride under an elevated pressure.An auxiliary catalyst of iodine, iodine chloride or a metal chloride can be incorporated to improve the chlorination.
