The investigation of oxidative bleaching performance of peripherally Schiff base substituted tri-nuclear cobalt-phthalocyanine complexes was written by Sen, Pinar;Yildiz, S. Zeki. And the article was included in Inorganica Chimica Acta in 2017.Name: N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) This article mentions the following:
This study covers the functional complexes of tetrakis [4-(salicylhydrazone)phenoxy] phthalocyaninato cobalt (II) (5) which was the macro mol. Schiff base ligand and synthesized through a multistep reaction sequence starting first with the cyclotetramerization of 4-[4-(1,3-Dioxolan-2-yl)phenoxy]-phthalonitrile (2). Then, the de-protection of tetra acetal groups of Tetrakis[4-(1,3-dioxolan-2-yl)phenoxy]phthalocyaninato cobalt (II) (3) to the aldehyde functionality in acetic acid/FeCl3 system to yield the Tetrakis(4-formylphenoxy)phthalocyaninato cobalt(II) (4) and then its condensation with salicylhydrazide gave to 5. Finally, CoPc-bis(salicylhydrazone)phenoxymanganese (III) (6), CoPc-bis(salicylhydrazone) phenoxycobalt(III) (7) and CoPc-bis (salicylhydrazone)phenoxy nickel(II) (8) were synthesized using with the related MnCl2·4H2O, CoCl2·6H2O, Ni(CH3COO)2 salt in basic conditions in DMF. FTIR, UV-visible, MS spectra and elemental anal. were applied to characterize to prepared compounds 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). The prepared catalysts showed better bleaching performance at 25° than to that of tetraacetylethylenediamine (TAED) bleach activator com. used in powder detergent formulations. In the experiment, the researchers used many compounds, for example, N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4Name: N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide)).
N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide) (cas: 10543-57-4) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Name: N,N-(Ethane-1,2-diyl)bis(N-acetylacetamide)
