Abstract

Dyes of the phthalocyanine series are made by heating phthalocyanines with organic acid halides. As accelerators there may be used the halides of iron, aluminium, zinc, arsenic, antimony, phosphorus and copper and also sulphuric acid. When starting from metal-free phthalocyanines, metal may be introduced into the phthalocyanine nucleus at the same time. Acid halides specified are acetyl-, chloracetyl-, propionyl-, butyryl-, oxalyl-, benzoyl- and phthalyl chlorides, phthalic acid - 4 - sulphochloride, p-toluenesulphochloride; halides of acids of the naphthalene, anthracene or anthraquinone series, e.g. 1-naphthoyl chloride, naphthalene - 1 - sulphochloride, 1 - naphthol - 2 - carboxylic acid-4-sulphochloride, anthraquinone-1-sulphonic- or carboxylic acid chloride or 1-nitroanthraquinone - 2 - carboxylic acid chloride; halides of heterocyclic acids, e.g. pyridine carboxylic acid chlorides. Diluents may be used such as carbon tetrachloride, tetrachlorethane, di- and trichlorbenzenes, nitrobenzene, pyridine, quinoline or phthalic anhydride, common salt, sodium sulphate, kieselguhr, mixtures of aluminium halides and alkali metal salts or aluminium halide-sulphur dioxide addition compounds. Green-blue to green products are obtained. In examples: (1) and (6) metal-free phthalocyanine (cf. Specification 410,814) is heated with benzoyl chloride or p-toluenesulphochloride in nitrobenzene or trichlorbenzene in presence of antimony trichloride; (2), (3), (7), (10) copper phthalocyanine is heated with benzoyl chloride in presence of copper meal with or without nitrobenzene, with a mixture of aluminium and sodium chlorides and 2 : 5-dichlorobenzoyl chloride or phthalyl chloride or 1-anthraquinonesulphochloride or 1-nitroanthraquinone-2-carboxylic acid chloride; (4) and (5) copper phthalocyanine sulphonic acid sodium salt is heated with oxalyl or benzoyl chloride in presence of sodium sulphate. Cobalt, nickel, zinc and aluminium phthalocyanines are also specified as starting materials.
