标题 :Beta-chloroethylsulfonylmethyl-benzoic halides as intermediates

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:A method for removing SO x from a gas by using a compound alcohol-amine solution is provided. The compound alcohol-amine solution is made by mixing ethylene glycol and/or polyethylene glycol with hydroxyl and/or carboxyl organic compound having basic group containing nitrogen. The compound alcohol-amine solution is contacted with the gas containing SO x to absorb the SO x in the gas, wherein x=2 and/or 3. The compound alcohol-amine solution with absorbed SO x is regenerated by one or more of heating method, vacuum method, gas stripping method, ultrasonic method, microwave method, and radiation method to release by-products of sulfur dioxide and sulfur trioxide, and the regenerated compound alcohol-amine solution is recycled for use. This method can be used for removing SO x from flue gas, burning gas, coke-oven gas, synthesis waste gas from dyestuff plants, sewage gas from chemical fiber plants, and other industrial raw material gases or waste gases containing SO x .
