Azo dye Chemische Eigenschaften,Einsatz,Produktion Methoden
Definition
Any of a broad series of synthetic dyes that have –N=N– as a chromophore group. They are produced from amino compounds by diazoti- zation and coupling. Over half of the commercial dyestuffs are in this general category. By varying the chemical composition it is possible to produce acid, basic, direct, or mordant dyes. This general group is subdivided as monoazo, disazo, trisazo, and tetrazo according to the number of –N=N– groups in the molecule. Examples are Chrysoidine Y, Bismarck Brown 2R, and Direct Green B.
