Dyestuffs containing ternary sulphonium or quaternary ammonium radicals

摘要

b - (p-aminobenzene-sulphonylamino) ethyl-b -oxyethyl-dimethylammonium chloride is made by reduction of the corresponding nitro derivative prepared by condensing N-(b -oxyethyl)dimethylamine with N-(b -oxyethyl)-p-acetylaminobenzene-sulphonamide. The latter is obtained by reacting b -chlorethylamine with p-acetylamino-benzene sulphochloride prepared by sulphochlorination of acetanilide. m-aminobenzyl-b -oxyethyl-dimethyl-ammonium methosulphate is made by reduction of the corresponding nitro derivative which is prepared by quaternising m - nitrobenzyl - b - oxyethyl-methylamine with dimethyl sulphate. 2-methyl-5-aminobenzene-sulphonic acid-g -(N-methyl - N - b - oxyethylamino)-propylamide is made by reduction of the corresponding nitro derivative prepared by reacting 2-methyl-5-nitrobenzene-sulphochloride with N-methyl-N-oxyethyl-propylene-1 : 3-diamine.ALSO:The invention comprises dyes of the formula:- where F is the radical of an organic dyestuff, R is alkylene or cycloalkylene, R2 is a straight or branched chain alkylene radical with up to 3 carbon atoms in the straight chain between R1 and Y, R1 is or , R3 and R4 are aliphatic, cycloaliphatic, aromatic or aralphatic substituents or R3 and R4 together with the nitrogen atom form a heterocyclic ring, Y is halogen or a hydroxy group esterified with an inorganic or sulphonic acid, and n is a whole number. Dyes specified for F are those of the azo, azaporphin, anthraquinone, triphenyl methane, oxazine or azomethine series. Inorganic acids specified in respect of Y are sulphuric and phosphoric. The dyes are made by esterifying a dye of the above formula where Y is hydroxy, by reacting an amine containing the group with a dyestuff sulphonic acid chloride or carboxylic acid chloride, or by diazotising and coupling diazo and coupling components containing the group The dyestuffs dye and print textile materials of natural of regenerated cellulose, in conjunction with an alkali and heat treatment, wool, silk and polyamide fibres in a variety of shades.
