Abstract
(DE)
Die vorliegende Erfindung betrifft ein Verfahren zur Veränderung, Abbau, oder Bleiche von Lignin, ligninhaltigem Material oder ähnlichen Stoffen unter Einsatz von Oxidationskatalysatoren und geeigneten Oxidationsmitteln, bei dem diese Katalysatoren in Kombination mit aliphatischen, cycloaliphatischen, heterocyclischen oder aromatischen NO-, NOH- oder (A)-haltigen Verbindungen eingesetzt werden.
(EN)
The present invention pertains to a process for modifying, breaking down or bleaching lignin, material containing lignin or like substances using oxidation catalysts and suitable oxidizing agents wherein these catalysts are used in combination with aliphatic, cycloaliphatic, heterocyclic or aromatic compounds containing NO, NOH or (A).
(FR)
Ce procédé de modification, de dégradation ou de blanchiment de la lignine, de matériaux contenant de la lignine, ou de produits similaires, fait intervenir des catalyseurs d'oxydation et les agents d'oxydation appropriés. Les catalyseurs utilisés sont associés à des liaisons aliphatiques, cycloaliphatiques, hétérocycliques ou aromatiques contenant NO, NOH ou (A).
