    摘要: Cyanamide compounds corresponding to the following formula ##STR1## in which R and R' each represent C.sub.1 -C.sub.6 -alkyl, cyclohexyl and benzyl, are used as activators for inorganic per compounds. They are preferably used in the mildly alkaline range at temperatures below 45.degree. C. Applications include the bleaching of textiles and hard surfaces, the oxidation of organic and inorganic intermediate products, and disinfection.

    摘要: Diperoxyalkanedioic acids and aromatic peroxycarboxylic acids are prepared by reacting a dialkanoic acid or an aromatic carboxylic acid with hydrogen peroxide in sulfuric acid and then producing a desensitizing agent for the peracid in situ by adding alkali metal hydroxide, alkali metal aluminate or an alkaline earth metal hydroxide so that the filtrate is free of sulfuric acid. The resulting salt coats the peracid and the product is desensitized and stable in storage.
