Abstract

Monochloro copper phthalocyanine is produced by heating phthalodinitrile and copper (II) chloride in nitrobenzene in the presence of 0.05-0.5 mole of a tertiary aromatic base to each mole of CuCl2 at 195-211 DEG C. The ratio of phthalodinitrile to CuCl2 is preferably 4:1 to 3.5:1 and the specified bases are pyridine, piccolines, isoquinoline and, especially, quinoline. Examples are given.
