Abstract

Abstract The oxidation of primary aromatic amines, p-methylaniline, p-ethylaniline and p- chloroaniline to the corresponding azo-and azoxy-compounds has been observed in ultrasound and/or microwaves systems. The individual irradiation of microwaves and its simultaneous irradiation with ultrasound obviously elevate the conversion of amines, as compared with the individual irradiation of ultrasound and the heating in a plain water ...
