Abstract

333,559. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 9, 1929, Sulphonic acid amides and carboxylic acid amides soluble in water and containing one or more free sulpho-groups but no nitro group or free amino or hydroxy group are made by condensing an aromatic sulphonic or carboxylic acid halide (2 mols.) with an aromatic diamine (1 mol.), at least one of the reacting components being substituted in m-position to the sulphonic or carboxylic acid halide or to the amino group. Bis-1 : 2- dichlorobenzene-4-sulpho-2<1> : 4'-tolylenediamide-6-sulphonic acid and bis-1 : 2-dichlorobenzene-4-sulphobenzidide-m-m<1>-disulphonic acid of Specification 324,962 are excluded. The products are suitable for reserving agents for wool or silk against substantive dyestuffs. In examples, (1) 1 : 3-phenylenediamine-4-sulpho acid is condensed with 2: 4-dichlorobenzoyl chloride, (2) benzidine-m-m<1>-disulpho acid with 1 : 2-dimethylbenzene-4-sulphochloride, 2-chlor-1-toluene-4-sulphochloride or 1 : 2 : 3-trichlorobenzene-4-sulphochloride, (3) benzidine-m-m<1>-disulpho acid is condensed with 4 - nitro - 1-chlorobenzene-2-sulphochloride (or m-nitrobenzenesulphochloride), the product reduced and condensed with 1 : 2-dichlorobenzene-4-sulphochloride (2 mols.), (4) bis- 3-aminobenzene-1-sulphonylbenzidine-m-m<1>- disulphonic acid is condensed with m-nitrobenzenesulphochloride, the product reduced and condensed with 1 : 2 - dichlorobenzene - 4 - sulphochloride; the original starting material i.e. benzidine-m-m<1>-disulpho acid may be replaced by tolidine-m-m<1>-disulpho acid or p-p<1>-diaminostilbene-o-o<1>-disulpho acid or by aminodiaryl derivatives having other bridge bonds e.g. 4: 4'-diaminodiphenylamine-2-sulphonic acid, (5) 2: 2'- dichlorobenzidine is condensed with the semichloride of m-sulphobenzoic acid. The Provisional Specification refers also to the condensation of aromatic sulphonic, or carboxylic acid halides with aromatic amines in general. Specification 333,554 is referred to. Sulphochlorides. - 1 : 2-Dimethylbenzene-4- sulphochloride, 2-chloro - 1 - toluene - 4 - sulphochloride, 1 : 2 : 3-trichlorobenzene - 4 - sulphochloride, 4-nitro-1-chlorobenzene-2-sulphochloride and 1 : 2- dichlorbenzene-4-sulphochloride are made by treating respectively with chlorosulphonic acid o-xylene, 2-chloro-1-toluene-4-sulphonic acid, 1 : 2 : 3-trichlorobenzene, 4-nitro-1- chlorobenzene-2-sulphonic acid and 1 : 2-dichlorobenzene or its 4-sulphonic acid.
