Desai, C. K. published the artcileSynthesis of azo dyes using 4-amino-2,4′-dichlorodiphenyl ether and their application on wool, nylon and silk fibres, Category: pyrazoles-derivatives, the publication is Oriental Journal of Chemistry (1999), 15(2), 381-382, database is CAplus.
New azo acid dyes using 4-amino-2,4′-dichlorodiphenyl ether as the diazo component and pyrazolones as the coupling components were synthesized. The dyes were characterized by elemental anal. and IR spectra. The dyeing properties on various textile fabrics were investigated. The dyes were water soluble and applied at 90-100°C on cotton, silk, nylon, and wool.
Oriental Journal of Chemistry published new progress about 14580-22-4. 14580-22-4 belongs to pyrazoles-derivatives, auxiliary class Organic Pigment, name is 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, and the molecular formula is C10H9ClN2O, Category: pyrazoles-derivatives.
