Abstract

4 - Amino-2:6-bis(b -sulphatoethylsulphonylmethyl)-toluene is made by sulphating 4-amino - 2:6 - bis(b - hydroxyethylsulphonylmethyl)-toluene obtained by reduction of the corresponding 4-nitro compound. The latter is obtained by oxidation of 4-nitro-2:6-bis(b -hydroxyethylmercaptomethyl)-toluene prepared by reacting 2:6 - bis(chloromethyl) - 4 - nitrotoluene with mercaptoethanol. 4-Hydrazino-2:6 - bis - (b - sulphatoethylsulphonylmethyl) toluene and 4-hydrazino-2:6-bis(b -hydroxyethylsulphonylmethyl)-toluene are made by diazotising and reducing the corresponding 4-amino compounds.ALSO:The invention comprises dyestuff mixtures of the formula:-<FORM:0917104/IV (b)/1> wherein A is a non-phthalocyanine dyestuff moiety, X is a bridging link containing up to 3 linking atoms selected from C, S, O and N and mixtures thereof, Y and Z are each hydrogen, lower alkyl, lower alkoxy or -CH2SO2CH2CH2OSO3M, M is hydrogen or an alkali metal, alkaline earth metal, ammonium or amine cation, n1 has an average value of 0 to 3 and n2 has an average value of 1 to 4. The residue A may be of the monoazo, disazo, polyazo, anthraquinone, nitro, thiazole, stilbene, azoic, di- or triphenylmethane, xanthene, acridine, azine, oxazine, thiazine, benzophenone, benzo- or naphthoquinone, indigo, thioindigo, sulphur dye or cyanine dye series. Examples illustrate dyes of the anthraquinone and dioxazine series. The bridging link X may be -SO2NR-NR, -O-, -NRSO2-, -SO2 NRNH-, -CH2-, -C2H4-, -CH2SO2-, -CH2NR-, -CH2S-, -CH2O-, -CO-, -S-, -CONH-, -NHCO- or -SCH2-. Dyes of the above formula may be made by reacting a compound of the formula shown in the right-hand bracketed portion above where X is amino or the corresponding hydroxyethylsulphonylmethyl compound with a dyestuff which contains 1 to 4 nuclear sulphochloride groups and 0 to 3 nuclear sulphonic acid groups or with a dyestuff which may or may not be sulphonated but which contains at least one halogen substituent and, if necessary, esterifying the hydroxy groups or sulphonating the radical A. Also a dyestuff may be chloromethylated and reacted with an aminobenzene containing at least one hydroxy- or sulphatoethyl-sulphonylmethyl group, or 4-hydrazino-2:6- bis(b - hydroxyethylsulphonylmethyl) toluene or its sulphate ester may be reacted with a chlorosulphonated dyestuff. The dyestuffs dye and print cellulose fibres by application to the fibre and curing at temperatures above about 220 DEG C. They also dye and print wool, silk, casein, zein, nylon and polyurethane fibres. Specification 733,471 is referred to.
