标 题 :Process for the preparation of aromatic amines
发明人：DE BESSET AMAURY P
权利人:CIBA GEIGY CORP
摘要:The invention relates to a process for the preparation of compounds of formula (1) wherein R is unsubstituted or substituted C1-C4alkyl or unsubstituted or substituted phenyl, X is hydrogen or unsubstituted or substituted C1-C4alkyl, and Y is unsubstituted or substituted C1-C4alkyl, which process comprises subjecting compounds of formula (2) wherein R, X and Y are as defined for formula I, to catalytic hydrogenation in the alkaline pH range. The compounds obtained by the process of this invention are suitable intermediates for the synthesis of dyes.

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.

摘要:The present teachings relate to a composition comprising a functionalised dye and a diallylamine comonomer, and the use of such compositions in methods of colouring a substrate. The present teachings provide improved bonding of a dye to a substrate, and preferably allow colouring to be conducted entirely in the presence of an aqueous solvent.
