摘要:已经开发了一种有效的铁催化氧化降解方法,该方法是在碱性ph下使用聚合物负载的三溴化物试剂分别将对环境有害的偶氮染料和靛蓝染料分别选择性转化为硝基芳烃和氨基芳烃羧酸(邻氨基苯甲酸).已开发出原位反应生成的和分离的(定义的)氯-铁(II)-吡啶-吡啶羧酸羧酸盐[fe(tpy)(pic)cl]催化剂体系,并发明了其催化功能用于降解过程.已筛选出不同的氮和氧配体以开发最佳催化剂体系,最后我们一起探索了吡啶2-羧酸和三联吡啶配体,发现是最佳的.值得注意的是,原位已经发现,所产生的和确定的催化剂体系对两种染料的氧化降解具有相似的催化活性是更有效的.结果,整个氧化降解过程都使用fe(tpy)(pic)cl催化剂体系进行,整个过程利用有效的催化方法选择性氧化偶氮和靛蓝的-nn-和-cc-键.染料分别.已经对该反应进行了详细的催化,机理和动力学研究.有趣的是,两种染料都在相同的动力学模式下以共同的氧化降解机理进

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.
