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:PCT No. PCT/DK90/00196 Sec. 371 Date Mar. 24, 1992 Sec. 102(e) Date Mar. 24, 1992 PCT Filed Jul. 30, 1990 PCT Pub. No. WO91/02254 PCT Pub. Date Feb. 21, 1991.A method and apparatus for quantitatively monitoring a chemical component dissolved in a liquid medium utilize the creation, in a measurement cell, of an interface zone between the liquid medium and an analytical reagent or reference solution. The concentration or amount of the chemical component are determined by the measurement of a value of a measurement parameter in the interface zone, and the derivation from that value of the concentration or amount of the component in comparison with a baseline or reference value measured for the reagent or reference solution alone. Matrix effects and ghosting errors are avoided. The method and apparatus can be used advantageously for on-line optimization and control of industrial, chemical and biological processes, such as chemical reactions in progress, coupling reactions for the synthesis of azo compounds, and the monitoring of in vivo or in vitro biological systems as well as for conventional analytical purposes.
