The investigation of oxidative bleaching performance of peripherally Schiff base substituted tri-nuclear cobalt-phthalocyanine complexes

Abstract

The bleaching performances of the prepared phthalocyanine compounds (3-8) were examined by the degradation of Morin as the hydrophilic dye which characterized the wine stains on the fabrics. Progress of the degradations in the catalysts (3-8)H2O2 combination in basic aqueous solution conditions was investigated by using online spectrophotometric method (OSM). It was found that the prepared catalysts showed better bleaching performance at 25 degrees C than to that of tetraacetylethylenediamine (TAED) bleach activator commercially used in powder detergent formulations.
