    摘要: Disclosed is an oxidizing system comprising a macrocyclic metal complex, an oxidizing agent and an oxidation-enhancing compound. This oxidizing system is useful under a wide variety of reaction conditions for oxidizing oxidizable substances by contacting the oxidizable substance with the specific oxidizing system. An example of a possible use is in a process for removing excess, unfixed dye from textile materials after a dyeing.

    摘要: In the preparation of substituted 4,4'-diaminostilbene-2,2'-disulfonic acid salts a clear increase in the reaction rate may be achieved by carrying out the reaction of the tetrachlorine derivative (III) with the aniline (IV) in the presence of the amine (VI) as acid-absorber.
