METHOD FOR PREPARING METAL COMPLEX OF TETRA-(5,8-DIHYDROXY)-ANTHRAQUINONE PORPHYRAZINE Russian patent published in 2006 - IPC C07F1/08 C07F15/00 C09B47/00

Abstract RU 2277098 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to the improved method for preparing metal complexes of tetra-(5,8-dihydroxy)-anthraquinone porphyrazine. Method involves interaction of 2,3-dicarboxy-5,8-dimethoxyantraquinone with urea, salt of corresponding metal in the presence of ammonium molybdate and chloride and the following hydrolysis of prepared metal complex of tetra-(5,8-dimethoxy)-anthraquinone porphyrazine. Prepared metal complexes can be used as catalysts, dyes and in another branches of science and technique. Method provides enhancing yield of the end product up to 24%.

EFFECT: improved preparing method.
