Abstract
1456989 Purifying copper phthalocyanines HOECHST AG 21 Dec 1973 [22 Dec 1972] 59648/73 Heading C4P Copper phthalocyanines are purified by adding to 84 to 88% sulphuric acid, subjecting the copper sulphate suspension formed to crystal growth at 60-100 C., under an inert gas atmosphere, e.g. nitrogen or argon, isolating the copper phthalocyanine sulphate and recovering the copper phthalocyanine in the α- modification by addition of water. Crystal growth takes place for at least one hour. Small amounts of nickel, cobalt and iron phthalocyanines may be present and the copper phthalocyanines may be substituted, e.g. by halogen. Up to 10 times by weight of acid based on the weight of copper phthalocyanine may be used and the copper phthalocyanine sulphate may be isolated by optionally diluting with water to about 80% acid strength and then filtering. Acid of appropriate strength may be recycled and if contaminated, may be regenerated.
