Process for producing highly chlorinated copper phthalocyanine |
摘要 |
A highly chlorinated copper phthalocyanine is produced by chlorinating a copper phthalocyanine in the presence of a catalyst for chlorination in a solvent by charging chlorine under an elevated pressure. The chlorination is carried out in an inert organic solvent incorporating chlorosulfonic acid and/or pyrosulfuryl chloride at a ratio of 1 to 30 wt. % based on said inert organic solvent which maintain dispersibility of said resulting highly chlorinated copper phthalocyanine.
