RECEIVING METHOD OF METAL PHTHALOCYANINE Russian patent published in 2009 - IPC C07D487/22

Abstract RU 2352571 C1

FIELD: metallurgy.

SUBSTANCE: method is implemented by means of interaction phthalic anhydride or its mixture with derivative phthalic acid with carbamide and metal salt at the temperature 190-220°C at presence of catalyst in organic solvent medium, corresponding technological mixture of diisopropyl benzol. By described method there are received phthalocyanine of copper, cobalt, iron, vanadyl, nickel and tin of high-fidelity with high yield. After implementation of condensation constructio solvent is vacuum removed.

EFFECT: it is improved method of receiving metal phthalocyanine.
