Synthesis of octochlorine-substituted complexes of cobalt(II) and copper(II) with phthalocyanine

A modified method for the synthesis of metallooctachlorophthalocyaninesand methods their purification based on sequential treatment with hydrochloric acid (10%) sodium hydroxide (2M), then again (10%), pyridine (O.S.C.) in 1,2,4-trichlorobenzene as a solvent is presented. As result, degree copper ion complexes was achieved, 99% versus best result using known literature 93%, cobalt purity 98% 88%. The yield products also higher than and amounted to 78, -43 compounds. Physico-chemical have established that after final stage purification-pyridine treatment, impurities are removed, including cyanuric acid, decomposition product urea, results elemental analysis carbon, hydrogen, nitrogen conducted ThermovomTypFlashEA 1112 analyzer (II), (II) phthalocyanine, assignment bands IR spectra recorded KBr tablets Nicolet IR-200 FT -IR spectrophotometer, UV-the sulfuric solutions metallooctachlorophthalocyanines taken Varian, UV -Vis/NIR spectrometer.
