PRODUCTION OF DIHALOGENOTITANIUM PHTHALOCYANINE, OXYTITANIUM PHTHALOCYANINE USING THE SAME AS RAW MATERIAL AND ELECTROPHOTOGRAPHIC PHOTORECEPTOR USING THE OXYTITANIUM PHTHALOCYANINE

摘要

PROBLEM TO BE SOLVED: To provide a method for easily producing a dihalogenotitanium phthalocyanine in high purity and yield. ;SOLUTION: In the production of a dihalogenotitanium phthalocyanine, a solvent different from the reaction solvent is added to the reaction system after the completion of the reaction of o-phthalodinitrile with a titanium compound, and the dihalogenotitanium phthalocyanine is taken out. Alternatively, in the production of the dihalogenotitanium phthalocyanine, a mixed solvent consisting of at least two kinds of solvents is used as a solvent for the reaction of o-phthalodinitrile with a titanium compound.;COPYRIGHT: (C)1997,JPO
