Patent

CA 2196902

Bleaching compositions are provided that comprise a nitrile containing compound that has the nitrile bonded to a quaternary nitrogen through a methylene unit (where one or both of the normal hydrogens can be substituted), and two of the quaternary nitrogen bonds are part of a saturated ring. This saturated ring contains from two to eight atoms in addition to the quaternary nitrogen. A source of active oxygen will react with the nitrile for bleaching applications. Particularly preferred nitrile containing compounds are N-alkyl morpholinium acetonitrile salts.

L'invention se rapporte à des compositions de blanchiment renfermant un composé contenant du nitrile où le nitrile est lié à un azote quaternaire par l'intermédiaire d'une unité de méthylène (l'un des deux ou les deux hydrogènes normaux pouvant être substitués), et où deux des liaisons de l'azote quaternaire font partie d'un anneau saturé. Cet anneau saturé comporte de deux à huit atomes en plus de l'azote quaternaire. Une source d'oxygène actif réagira avec le nitrile pour les applications de blanchiment. En particulier, le nitrile préféré contient des composés qui sont des sels d'acétonitrile de morpholinium N-alkyle.
