摘要:The description relates to azo compounds corresponding to formula (1) below, having fibre-reactive properties and making valuable dyes. They can dye hydroxy and/or carbonamide group-containing synthetic and natural materials, especially fibre materials, like wool and especially cellulose fibre materials in bright colours. Formula (1) in which: M is hydrogen or a salt-forming metal like an alkaline metal; K is a residue of general formulae (2A) or (2B) in which: E is the residue of an intermediate component common in disazo dyes which can act as a coupling and as a diazo component, e.g. the residue of a 1-(aminophenyl) or -amino-naphthyl) pyrazolon, aminonaphthol, anilin or 1-amino naphthalin compound; v is the figure zero or 1; K is the residue of a water-soluble coupling component, preferably from the naphthol, aminonaphthol, anilin, pyrazolon, hydroxypyridon and acetoacetyl arylide series, whereby this coupling component contains 1 or 2 fibre-reactive groups of the vinyl sulphonate series; D is a benzol or naphthalin residue, whereby its substituents R?1 and R?2 are common ones in azo dyes, e.g. (besides hydrogen) lower alkyl, lower alkoxy, halogen, sulpho and carboxyl; the group -SO2?-Y is a fibre-reactive group of the vinyl sulphone series; a is the figure zero, 1 or 2; and k is the number 1 or 2. A description is also given of the compound 2-amino naphthaline-1-sulphonic acid-6-carboxylic acid which may be used as a pre-product in the production of dyes, e.g. as diazo component in the synthesis of dyes of general formula (1).

标题 :Beta-chloroethylsulfonylmethyl-benzoic halides as intermediates
发明人：SCHLAEFER LUDWIG; HAEHNLE REINHARD
权利人:HOECHST AG
摘要:New beta -chloroethylsuflonylmethyl-benzoic acid halides which can serve as fibre-reactive anchors for thesynthesis of novel organic, water-soluble compounds, preferably dyestuffs, having fibre-reactive and fibre-finishing properties, such as preferably dyestuff properties, and containing, as a fibre-reactive group, one or two beta -chloroethylsufonylmethylbenzoic acid amide groups. For the synthesis of these novel fibre-finishing compounds, said new beta -chloroethylsulfonylmethyl-benzoic acid halide compounds are reacted with an organic, water-soluble compound having fibre-finishing properties and continuing one or two amino groups. Also precursors of the fibre-finishing, fibre-reactive compounds, containing said beta -chloroethylsulfonylmethyl-benzxoic acid amid grouping, can be employed for their synthesis. The novel fibre-finishing compounds can be applied onto suitable fibre materials, such as especially cellulose fibre material and natural or synthetic polyamide fibre materials, and fixed on these fibre materials in a manner similar to application and fixation methods usual in the technique for fibre-reactive compounds. The fibre-finished material, such as dyed material, shows very good wet fastnesses.

标题 :Process for producing concentrated aqueous solutions of anionic azo dyes

摘要:PCT No. PCT/EP91/01830 Sec. 371 Date Mar. 26, 1993 Sec. 102(e) Date Mar. 26, 1993 PCT Filed Sep. 25, 1991 PCT Pub. No. WO92/06140 PCT Pub. Date Apr. 16, 1992.If highly concentrated aqueous solutions of azo dyes are prepared directly by diazotization and coupling reactions, appreciable difficulties generally result as a consequence of the fact that the diazotization and coupling reactions give rise to viscous phases which lead to stirring problems in the reaction apparatus used, which in turn results in an incomplete synthesis. The novel process for preparing concentrated aqueous dye solutions of an anionic dye in an aqueous medium overcomes this disadvantage by carrying out the diazotization of the aromatic amine diazo component and/or the coupling reaction between the diazonium salt and the coupling component in the presence of an auxiliary which exerts a viscosity-reducing effect on pasty phases. Examples of such auxiliaries are optionally alkyl-substituted naphthalenesulfonic acid-formaldehyde condensation products, ligninsulfonates, polyacrylates and copolymers of maleic anhydride and methacrylic acid or acrylic acid.
