Abstract
15,706. Urquhart, R. J., [Chemische Fabriken vorm. Wieler-ter Meer]. Aug. 3. Azoxy, azo, and hydrazo compounds and amines are produced successively from nitro compounds, or either of these compounds is produced from one of the corresponding more highly oxidized compounds, by heating such compounds with iron and an alkali, such as caustic soda, in a vessel fitted with a stirring and cooling apparatus. Examples are given in which o-nitrotoluene is reduced to azoxytoluene, o-nitroanisol is reduced to o-azoanisol, p-nitroacetanilide is reduced to p-phenylenediamine, and amidoazobenzene is reduced to p-phenylenediamine and aniline. An example is also given in which nitrobenzene is reduced to azoxybenzene, azobenzene, hydrazobenzene, and aniline, successively, by successive additions of suitable quantities of the reducing-agent, the progress of the reaction being checked by observations of the solidifying point of the products.
