Abstract

Compounds containing ethenesulphonamide groups are prepared and used in the preparation of azo dyestuffs (see Group IV(c)). Ethenesulphonyl - (3-aminophenyl)-amide is prepared by the reduction of ethensulphonyl-(3-nitrophenyl)-amide (Specification 686,061, Example 5) in aqueous calcium chloride with iron powder. 1 - ethenesulphonamido - 8 - naphthol-3:6-disulphonic acid sodium salt is prepared in solution by treating an aqueous solution of 1-amino-8-naphthol-3:6-disulphonic acid sodium salt with a solution of ethenesulphonyl chloride in acetone. 1-(31-ethenesulphonamidophenyl)-3-methyl-5-pyrazolone is prepared by reacting 1-(31-aminophenyl) - 3 - methyl-5-pyrazolone with carbyl sulphate in 1 : 2-dichloroethane. 4 - amino-41-ethenesulphonylamido-diphenylsulphide is prepared by reacting 4-nitro-1-amino-diphenyl sulphide with carbyl sulphate in 1 : 2-dichloroethane and reducing the nitrocompound with iron powder in aqueous calcium chloride solution. Specification 686,061 is referred to.ALSO:The invention comprises azo dyestuffs containing at least one ethene-sulphonamide group and at least one water-solubilizing group. The dyestuffs may be prepared by the usual diazotization and coupling reactions using suitable components or by acylation of aminoazo dyestuffs with agents which introduce an ethenesulphonyl radical, such as ethene sulphonic acid chloride and bromide and carbyl sulphate. The dyes may be used to dye cellulose, wool, leather, silk and linear polyamides in many shades, the dyeings being fixed by treatment with alkalis and heating. Many examples are described, the components specified including ethenesulphonyl-(3-or 4-aminophenyl)-amide, 4-amino- 41-ethenesulphonyl amido-diphenyl-sulphide or-sulphone or -ketone or -amine and diamino-diphenylmethane; 1-(phenyl or sulphophenyl)-5-pyrazolones, naphthol-sulphonic acids, aminonaphthol-sulphonic acids and N-acyl derivatives thereof, 8-hydroxyquinoline- 4-sulphonic acid and 2-ethenesulphonylamido- 5-naphthol- 7-sulphonic acid. Specifications 686,061, 712,037, 776,265 and 779,781 are referred to.
