Abstract
111,904. Sokal, S., (Kalle & Co. Akt.-Ges.). Dec. 14, 1916. Benzoquinone dyes.-Vat dyes are obtained by heating halogenbenzoquinones substituted by two residues of aniline, its homologues, or substitution products, with a metal in the presence of a suitable solvent or diluent. According to examples : -3 : 6 - dichlor - 2 : 5 - dianilidobenzoquinone is heated with copper powder in nitrobenzene; the product dyes wool yellowish-brown tints from a hydrosulphite vat; a similar product is obtained from the condensation product of chloranil with two molecules of o-toluidine; di-p-chloranilidodichlorbenezoquinone is heated with iron shavings and water under pressure; the product dyes wool yellow tints; the use of zinc instead of iron gives a product dyeing greenish-yellow tints. Specification 8886/12 is referred to.
