标题:偶氮染料结构与大鼠肝氧化还原酶活性的关系
摘要:使用大鼠肝偶氮还原酶系统测定各种偶氮染料的还原速率.降序排列的偶氮染料还原速率表示为每分钟/0.25克肝脏形成的芳基胺产物的nmol浓度为a菜红(33.2),偶氮磺酰胺(32.5),橙色g(12.4),1,2-二甲基-4-对-(羧基苯基偶氮)-5-羟基苯(cpa)(9.27),亮晶红色猩红色(8.00),磺基ry啶(7.27)和苏丹i(1.03).分配系数与其还原速率的比较表明,水溶性偶氮染料比脂溶性染料还原得更快.此外,对于在芳环上含有吸电子基团的那些染料,观测到更高的还原速率.

发明人：HAY ALLAN S; WANG ZHI Y
权利人:HAY ALLAN S; WANG ZHI Y
摘要:Aromatic sulfides including diarylsulfides and poly(arylene sulfides) are produced in a novel synthesis in high yield under moderate conditions by heating an aromatic disulfide in the presence of aromatic halide, in which the halide is chloride, bromide or iodide; the diaryl sulfides are useful precursors and starting materials for a range of compounds and the poly(arylene sulfides) are important high temperature engineering thermoplastics.

标题 :Process for the synthesis of nitrite ion-containing 1:1 complexes of cobalt and metallizable monoazo or azomethine compounds and such complexes
发明人：DORE JACKY
权利人:SANDOZ LTD
摘要:By metallization of metallizable monoazo or azomethine dyes with cobalt-donating compounds in the presence of a nitrite, especially NaNO 2 , 1:1 cobalt complexes containing a nitrite ion are obtained in a high degree of metallization which can be reacted with metallizable monoazo or azomethine dyes to give very homogeneous 2:1 cobalt complexes in a high degree of purity. This is particularly advantageous when asymmetrical 2:1 cobalt complexes are to be prepared. The process is particularly useful for the preparation of nitrite ion-containing 1:1 complexes of cobalt and a monoazo compound of the formula ##STR1## wherein X is --OH or --NHR, n wherein R is hydrogen or a substituted or unsubstituted alkyl, cycloalkyl, phenyl or naphthyl group, n Ring A is further unsubstituted or further substituted by at least one halo, nitro or optionally substituted alkyl, alkoxy or sulfamoyl substituent, and n The naphthalene ring is further unsubstituted or further substituted by at least one hydroxy, sulfamoyl or acylamino substituent.

摘要:The subject invention provides novel methods and apparatus for synthesizing carbohydrates of a desired structure. The subject synthesis methods include using carbohydrage-modifying enzymes to perform individual synthesis reaction steps and electrophoresis to purify the reaction products for possible further use as substrates in additional synthesis reactions. The subject invention also provides novel methods and apparatus for detecting carbohydrates of interest. The methods and apparatus for synthesizing or detecting carbohydrates involve the use of carbohydrate-modifying enzymes immobilized in a reaction matrix gel and fluorophore labelled substrates that may be removed from the reaction matrix gel by electrophoresis and subsequently analyzed or transferred to another reaction gel matrix. n The subject invention also provides methods for detecting and quantitating specific carbohydrate-modifying enzymes that might be present in a sample for analysis.

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.
