标题 :One-pot synthesis of reactive deep black
发明人：VRIEZEMA DENNIS MANUEL; KLEINE SIGRID ELISABETH; SMALLEGANGE MARTIN JAN
权利人:SPGPRINTS B V
摘要:A one-pot synthesis for preparing an aqueous reactive black mixture includes a) dissolving 2-[(4-aminophenyl)sulfonyl]ethanesulfonic acid (vinyl sulphone parabase ester) in water; b) diazotizing the dissolved vinyl sulphone parabase ester using excess nitrous acid or using excess nitrite and an acid, resulting in a diazonium salt and remaining nitrous acid; c) quenching the remaining nitrous acid with sulfamic acid; d) coupling the diazonium salt of step c) with 4-amino-5-hydroxy-2,7-naphthalenedisulfonic acid (H-acid) until the reaction is complete, resulting in Reactive Black 5 (RB 5) and remaining diazonium salt, e) coupling the remaining diazonium salt with 7-acetamido-4-hydroxy-2-naphthalenesulfonic acid (acetyl-J-acid) until the reaction is complete resulting in Reactive Orange 78 (RO 78); and f) obtaining the aqueous reactive black mixture.

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).

摘要:Low molecular weight 4,4'-diphenylmethane-uretdione-diisocyanates corresponding to the formula: +TR wherein n is a number from 0 to 1, are made by dimerizing diphenylmethane-4,4'-diisocyanate at a temperature of 50 DEG C. or less in a mixture of non-polar and moderately polar solvents in the presence of a dimerization catalyst. The dimerization product may then be worked up at low temperatures (i.e.,

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.
