Abstract
An aromatic primary diamine having no SO3H gps. is monoacylated by reacting a mineral acid salt of the diamine with an aliphatic acid anhydride in aq. medium. The anhydride is esp. of acetic or propionic acid and reaction is best effected in presence of 0.5-10 wt. % w.r.t. the diamine, of a surfactant. Better yields are obtd. than by reducing nitro monoacylamino cpds. Pref. diamine is m- or p-phenylenediamine.
