Kinetic Study of the Formation of the Colored Azo Dye (2,2'-(1,4-Phenylenebis (diazene-2,1-diyl)) bis (4-methoxyaniline)) From p-Anisidine

A kinetic study on the preparation of an azo dye from the reaction between 1,4-di ((E)-chlorodiazenyl) benzene and p-anisidine (4-methoxy-aniline), was conducted at 290 K, with a maximum absorption wavelength (lmax) of 398 nm. The reaction was carried out in an acidic medium (pH = 5.27), under optimal conditions determ...
