  • 摘要:In this paper, two novel alkali clearable disperse dyes were synthesized. 4-flourosulfonyl aniline and 2-nitro-4-flourosulfonyl aniline were utilized as the diazo components and 2- naphthol as the coupling component. The DSC, FTIR, 1HNMR and UV-Vis analyses were used to characterize the synthesized intermediates and dyes. The synthesized dyes were used to dye polyester fibers and their dyeing properties were studied. In addition, hydrolysis kinetic of the synthesized dyes in alkali media was studied. The results showed that the synthesized dyes have good properties on polyester fabrics. Hydrolysis of the synthesized dyes in alkaline media provides the replacement of reduction clearing process by alkali-clearing process. The elimination of sodium hydrosulphite will cause reduction of environmental pollution. The advantage of replacement of reduction clearing-method by alkali-clearing process will cause the prevention of producing toxic and carcinogenic compounds.
