Abstract

Symmetrical di-(arylamino)-hydroxybenzenes are manufactured by heating one molecular proportion of phloroglucinol with about two molecular proportions of an aromatic amine, if necessary in the presence of a diluent, e.g. xylene, at about 140 DEG C. in such a manner that the water formed during the reaction distils from the reaction mixture. The products are intermediates for the manufacture of dyestuffs. Examples describe the reaction of phloroglucinol with p-chloraniline, aniline, o-and p-toluidine, p-anisidine, m-xylidine (CH3 : CH3 : NH2=1 : 3 : 4), b -naphthylamine and m-nitraniline. In the last case a small quantity of the monoarylaminodihydroxybenzene is obtained as a by-product.
