A new kind of reactive dyes containing both monoazo and anthraquinone chromophores was obtained by using 1,4-bis((4-aminophenyl)amino)anthrancene- 9,10-dione as diazo component and 1-amino-8-naphthol-3,6-disulfonicacid (H-acid) derivatives as coupling components. The dyes were characterized by UV-Vis, IR, MS, 1H NMR and 13C NMR. The maximum absorption wavelengths of the dyes were all about 590 nm, which indicated that they were a kind of blue dyes. 1H NMR and 13C NMR results revealed that there were two kinds of tautomerisms in dye structure and a new conjugated system formed between the anthraquinone ring and the Ph azo linkage. D. functional theory (DFT) calculations also proved the formation of the new larger conjugated system from which the blue color was generated. The fixations of the dyes on cotton were over 88% and the light fastness reached 5 grade. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Computed Properties of C9H6Cl2N4).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Computed Properties of C9H6Cl2N4
