Synthesis of Compounds Containing Fluorine, Vinylsulfone Groups and Transition Metal Complexes and their Applications to Textiles

Abstract

A ligand which has reactive dye character and its transition metal complexes such as Cu(II), Co(II), Cr(III), Ni(II) containing vinylsulfone and fluorine groups were synthesized. The diazotation reaction has been studied at 0-5°C carefully. Completion of the reaction was monitored by the TLC method. FT-IR, UV,1H-NMR, TGA and microanalysis methods were used for determination of the synthesized compounds. We assumed that copper complex indicated dimeric structure based on magnetic susceptibility result. All the synthesized compounds which have dye character were applied on cotton, polyamide and nylon fibers. Their dyeing and fastness properties were investigated according to international standards. These properties gave good results for all synthesized dyes except light fastnesses of chromium and nickel complex dyes.

Copolymerization of 4‐vinylsulfonyl aniline with acrylamide and its application as macromolecular dye backbone

“…4-(Ethylsulfurate sulfonyl) aniline, an intermediate commonly used in the manufacture of reactive dyes, can be easily converted to 4-vinylsulfonyl aniline (VSA), which contains a polymerizable carbon-carbon double bond. 21 VSA can be copolymerized with other monomers. Furthermore, chromophores containing reactive groups can be introduced by modifying the aromatic amines in the VSA.…”

Removal of textile azo dyes with mixed biomass of Aspergillus niger and orange peel (Citrus sinensis L. Osbeck)

“…Among the reactive dyes which are widely used in the textile industry, can be cited the dyes Remazol Red (C25H15N7O16S5Na4Cl) and Remazol Black B (C26H21N5Na4O19S6), which have at least one chromophore azo(-N=N-) group and an electrophilic (reactive) group. They are capable of forming covalent bonds with the fibers, thus promoting the fixation of the dye to the fiber [6] .…”
