Synthesis and Application of 3-(6-((4-ethyl -2-hydroxyethyl)amino) phenyl)diazinyl)-1,3-dioxo-1H-benzo[de]isoquinolin-2-(3H)yl)propanoic acid as a Disperse Dye
A monoazo disperse dye based on naphthalimide was synthesized by using 3-(6-amino-1,3-dioxo-1H-benzo[de]isoquinoline- 2(3H)-yl) propanoic acid as a diazo component and N-ethyl-N-hydroxyethyl aniline as a coupling component. The synthesized dye was purified and characterized by FTIR, 1HNMR, DSC and UV-Vis spectroscopic techniques. Thespectrophotometric characteristics of the dye were investigated in various solvents. The results showed that the synthesized dye has a positive solvatochromism. Wavelength of maximum absorption and molar extinction coefficient in acetone were 524.3 nm and 34125 l mol-1cm-1, respectively. The synthesized dye was applied to nylon, polyester and acrylic fibers and the effects of temperature, time and build up were investigated. The results showed that the synthesized dye had a good build up on nylon which gave excellent wash and rubbing fastnesses and fair light fastness. J. Color Sci.
