I.G. Leverkusen Azobenzene
Abstract
Reduction of nitrobenzene to azobenzene with water and sodium amalgam obtained from mercury cells is described. The reaction is quite vigorous, and cooling water is used to maintain temperature at 80 deg C. The azobenzene produced melts at 70 deg C and has to be kept in steam-heated vessels. Nickel is only known material which will withstand the condition in the reactor. Production of amalgam is hindered because of inefficiency of mercury cells caused by high temperature and high amalgam concentration.
