Disperse Styryl and Azo Dyes for Polyester and Nylon Fibre: Synthesis, Optical Properties Having the 1,2,4-triketo Naphthoquinone Skeleton of natural dyes when used with synthetic fibres. Synthesis, spectral features and biological activity of some novel hetarylazo dyes derived from 6-amino-1,3-dimethyluracil some heterocyclic azo compounds have also found use as ligands to generate a special category of metal azo complexes which are exploited enormously in the manufacture of colorimetric The route of synthesis of dyes Cited by: Synthesis, biological activity and dyeing performance of some novel azo disperse dyes incorporating pyrazolo Several novel pyrazolopyrimidine azo compounds were achieved from diazotization of 4-aminoacetanilide and coupling with malononitrile and then refluxed with hydrazine hydrate to furnish 3,5-diamino Synthesis of the dyes Cited by: An overview is presented on thiazolylazo dyes and their analytical applications in the determination, preconcentration or separation of trace metal ions.
The article summarizes conventional analytical methods based on spectrophotometry, solid phase extraction, liquid chromatography and liquid–liquid and cloud point by: A new series of heterocyclic disperse dyes were prepared by diazotization of some 2-aminothiazole derivatives and subsequent coupling with indole compounds.
The dyes were characterized by UV-Vis, FT-IR, 1H NMR, and mass spectra (LC-MS). Solvent effects on their visible absorption spectra were estimated. The color of the dyes is discussed with respect to Cited by: Synthesis of Some Monoazo Disperse Dyes Derived from A series of thienylazo and thiazolylazo disperse dyes has been prepared from their corresponding coupling.

The fastness test to washing and light properties of samples (10a and 10b) dyed in glauber salt ranged from good 4 to excellent 5. Good light to washing fastness may be due to better dye penetration as well as good covalent fixation with cotton fabrics (Peters and Freeman, ).Effect of pH on percentage exhaustion: At 60°C the effect of pH on exhaustion is shown.
The present paper reports on the synthesis of an azo dye 4-(2-(oxoanthracen-9(10H)-ylidene)hydrazinyl)-N-(pyrimidinyl)benzenesulfonamide (dye1) and its inclusion complex with β- cyclodextrin (dye2).Spectral methods were applied to demonstrate the chemical structures of the synthesized azo dyes.
In this study the synthesis of azo dye 4-(2-(oxoanthracen-9(10H)-ylidene)hydrazinyl)- N -(pyrimidinyl) benzenesulfonamide (dye1) and its inclusion complex with β-yclodextrin (dye2) and their application on polyester fabric are described.
The chemical structure of the azo dye formed and the inclusion dye complex created were confirmed by FT-IR, 1H Cited by: 2.
