METHOD FOR PREPARING METAL COMPLEX OF TETRA-(5,8-DIHYDROXY-6-SULFO)-ANTHRAQUINONE PORPHYRAZINE

摘要

FIELD: chemistry of metalloorganic compounds, chemical technology.;SUBSTANCE: invention relates to the improved method for preparing metal complexes of tetra-(5,8-dihydroxy-6-sulfo)-anthraquinone porphyrazine. Method is carried out by interaction of 2,3-dicarboxy-5,8-dimethoxy-6-sulfoanthraquinone with urea and the corresponding metal salt in the presence of chloride and ammonium molybdate and the following hydrolysis of the synthesized metal complex - tetra-(5,8-dimethoxy-6-sulfo)-anthraquinone porphyrazine by its treatment with sodium hydroxide. Proposed metal complexes can be used as catalysts, dyes and in other fields of science and technique.;EFFECT: improved preparing method.;2 cl, 3 dwg, 4 ex
