Monoazo colorants

Analytical identification of monoazo colorants and the other decomposition products requires effective (analytical) methods of concentration, which is made possible by high performance liquid chromatography (HPLC). Prior to HPLC analysis, the pigmented medium was extracted for 20 hours with toluene in a soxhlet extractor. These analytical methods also showed that above 240°C, especially after prolonged exposure of the pigmented polymer material to heat, dichlorobenzidine (DCB) is also formed. [Pg.242]

A final example of a monoazo color is an orange fiber-reactive dye, prepared by diazotizing 2-amino-1,5-naphthalenedisulfonic acid, coupling it with Y-methyl-J-acid, and condensing with cyanuric chloride and then with ammonia. One chlorine atom remains for reaction with textile fibers bearing hydroxyl or amino groups. [Pg.896]
