    • This invention provides a method for activating peroxides, particularly hydrogen peroxide or hydrogen peroxide adducts and for thereby furnishing the said peroxides with excellent bleaching effects, cleaning effects, and sterilizing effects at low temperatures, by adding to the said peroxides an aromatic compound containing in the molecule one or several groups represented by the formula ##EQU1## wherein R is a substituted or unsubstituted monovalent aromatic group and X is either CO or SO.sub.2. The activation according to this invention is preferably carried out in an aqueous solution at a pH value ranging from 7 to 11, at a temperature below 40.degree.C.
    • 本发明提供了一种活化过氧化物,特别是过氧化氢或过氧化氢加合物的方法,由此通过向所述过氧化物中加入含有所述过氧化物的芳族化合物,从而使所述过氧化物在低温下具有优异的漂白效果,清洁效果和灭菌效果。 分子由式X-RCO-N ANGLE SO 2表示的一个或几个基团,其中R是取代或未取代的一价芳族基团,X是CO或SO 2。 根据本发明的活化优选在pH为7-11的水溶液中,在低于40℃的温度下进行。
