Synthesis, Characterization and Printing Application of Solvent Dyes Based on 2‐Hydroxy‐4‐n‐octyloxybenzophenone

Abstract

Solvent dyes have been prepared by the coupling of diazo solution of different aromatic amines with 2-hydroxy-4-n-octyloxybenzophenone. The resultant dyes were characterized by elemental analysis as well as IR and1H NMR spectral studies. The UV-Visible spectral data have also been discussed in terms of structure property relationship. The printing of all the dyes on cotton fiber was monitored. The result shows that better hue was obtained on printing on cotton fiber and it is resulted in yellow to reddish brown colorations which showed a good fastness to light, with poor to good fastness to washing, perspiration and sublimation, however it shows poor rubbing fastness.

Synthesis and Spectral Characterization of Lanthanide Complexes Containing Bidentate Schiff Base Derived From Pyridine-2-Carbaldehyde and 2-Hydrazinylquinoline

“…The UV electronic spectra of La(III), Pr(III), Nd(III), Tb(III) and Sm(III) metal ion complexes indicates the transition is shifted towards higher or lower frequencies which confirm the coordination of the ligand to the metal ions. La(III) metal complex shows absorption bands 20080 cm -1 assigned as LMCT transition [41][42][43].…”

Synthesis, Characterization, and Dyeing Performance of UV Protective Mono Azo Acid Dyes Based on 4-Hydroxybenzophenone

“…30 Benzophenone is an excellent UV absorber 31,32 that prevents the photo-degradation of many vinyl polymers. 33 Compounds such as 4-hydroxybenzophenone, 2,4-dihydroxybenzophenone, and 2-hydroxy-4-me-thoxybenzophenone bearing hydroxyl and methoxy (as auxochrome) groups and a keto (chromophore) group have widely used applications as a polymer additive. 34 In the literature, a few benzophenone-based acids, reactive, and disperse azo dyes are also reported.…”

Synthesis and application of UV ray’s protective mono azo acid dyes on Wool, Silk and Nylon

“…Benzophenone is an excellent UV absorber [12] , which prevents the photo degradation of many vinyl polymers [13]. Compounds 4-hydroxy benzophenone, 2, 4-dihydroxy benzophenone and 2hydroxy-4-methoxy benzophenone bearing hydroxyl and Methoxy (as auxochrome) groups and a keto (chromophore) group.…”

“…This compound has wide applications as a polymer additive [14]. In the literature few benzophenone based acid, reactive and disperse azo dyes are reported [9,13,15,16,17,18,19] There has been a progressive increase in the incidence of skin cancers, particularly that of cutaneous melanomas over the last few decades [20]. Evidence from various disciplines has implicated ultraviolet radiation (UVR) from the sun as an important factor in causing skin cancer.…”
