BLEACH ACTIVATORS |
摘要 |
New compounds useful as bleach activators as well as new percarboxylic acids, which may be formed as intermediates upon reaction of such activators with peroxygen bleach source in aqueous solution, include nitrogen-containing heterocyclic groups. Preferred activators are symmetrical derivatives of dibasic carboxylic acids, having N, N'diacyl N-heterocyclic groups usually lactams. They are produced by reaction of 2 moles of the lactam with one mole of dibasic acid chloride or anhydride.
