Synthesis and characterization of new azo saccharin derivatives dyes and their applications on different fibers

Azo is one of the most effective functional groups used to synthesis commonly colors and plays an important role in several applications of industrial dyes. More specifically, saccharin has been extensively used in the field of human food. In this paper, saccharin has been successfully implemented as a primary material for the preparation of new AZO dyes, which illustrates the novelty of this research. The chromophore system mainly consists of a group (-N = N-) associated with one or more different aromatic. The invented dyes are identified by spectroscopic that measured the stability of these dyes and evaluated the color of the polystyrene and nylon.6 on the fibers. The influence of the substitution groups on the stability of the color of newly prepared dyes is also investigated.
