Abstract

102,881. Imray, O., (Society of Chemical Industry in Basle). May 13, 1916. Disazo dyes.-Substantive o-oxydisazo dyes are obtained by coupling a tetrazotized diamine of the types (HO) (NH2) C6H3.X.C6H3 (NH2) (OH) or (HO) (NH2) C6H3.X.C6H4.NH2, wherein the hydroxy groups are in o-position to the amino groups and X = a diphenyl linking or the group CH2, HN.CO.NH, or CO, with two molecular parts of 2 : 5 : 7 - aminonaphthol sulphonic acid or a derivative thereof, or with one molecular part of this acid or a derivative thereof and one molecular part of any other component, or with two molecular parts of any component. Suitable diamines are 3 : 3<1>-dioxybenzidine, 3 : 3<1> - diamino - 4 : 4<1> - dioxydiphenyl, 3 3<1> - diamino - 4 : 4<1> - dioxydiphenylmethane, 3 : 3<1> - diamino - 4 : 4<1> - dioxydiphenylurea and its 5 : 5<1> - disulphonic acid, 3:3'- diamino - 4 : 4<1> - dioxydiphenylketone, and 3- oxybenzidine. Examples are given of the production of dyes from the following components 3 : 3<1> - dioxybenzidine, 2 : 5 : 7 - acid, and resorcin; 3 : 3<1> dioxybenzidine and two molecules of resorcin; 3 : 3<1> - diamino - 4 : 4' - dioxydiphenyl, 2 : 5 : 7 - acid, and resorein; 3 : 3<1> - diamino - 4 : 4<1> - dioxydiphenylmethane, 2 : 5 : 7 - acid, and resorcin; 3 : 3<1> - diamino - 4 : 4<1> - dioxydiphenylmethane and two molecules of resorcin; 3 : 3<1> - diamino - 4 : 4<1>-- dioxy - 5 : 5<1> - disulphodiphenylurea and two molecules of m-aminobenzoyl - 2 : 5 : 7 - acid ; 3 : 3<1> - diamino-4 : 4<1> - dioxydiphenylketone, 2 : 5 : 7 - acid, and resorcin; 3 - oxybenzidine, 2 : 5 : 7 - acid, and resorcin; thess products dye cotton redviolet, brown-red, red-brown, salmon-red, yellowbrown, lilac, mauve, and red-violet shades respectively. Specification 12250/15 is referred to. 3 : 3<1> - Dioxybenzidine is obtained by saponifying dianisidine with aluminium chloride. 3 : 3<1> - Diamino - 4 : 4<1> - dioxydiphenylmethane is obtained by condensing o-nitrophenol with formaldehyde and reducing the product. 3 : 3<1> - Diamino - 4 : 4<1> - dioxydiphenylketone is obtained by dinitrating dioxybenzophenone and reducing the product. 3 : 3<1> - Diamino - 4: 4<1> - dioxydiphenylurea is made from 4-nitro -2-aminophenol by successively acetylating, reducing, treating with phosgene, and saponifying. 3 : 3<1> - Diamino - 4 : 4<1> - dioxy - 5 : 5<1> - disulphodiphenylurea is obtained by treating 2-nitro-4- aminophenol - 6 - sulphonic acid with phosgene and reducing the product. Reference has been directed by the Comptroller to Specifications 11795/89, 15386/92, 20216/10, and 30284/10.
