METHOD FOR PREPARING COPPER TETRA-(3-AMINO-5-TERTIARY-BUTYL)PHTHALOCYANINE Russian patent published in 2006 - IPC C07D487/22 C07F1/08

Abstract RU 2272038 C1

FIELD: chemistry of metalloorganic compounds, chemical technology.

SUBSTANCE: invention relates to a method for preparing copper tetra-(3-amino-5-tert.-butyl)phthalocyanine. Method involves reduction of copper tetra-(3-nitro-5-tert.-butyl)phthalocyanine with 3-5-fold excess of hydrazine hydrate in the presence of palladium catalyst in medium of mixed solvent methanol-benzene in their ratio = 30:70, respectively. Invention provides enhancing the yield of the end product up to 97%.

EFFECT: improved preparing method, increased yield.
