Abstract (en)
[origin: EP0717143A1] System for transforming, degrading or bleaching lignin, lignin-contg. materials or similar materials, comprises a poly-component system comprising: (a) opt. ≥ 1 oxidation catalyst; (b) ≥ 1 oxidising agent; (c) ≥ 1 mediator selected from hydroxylamines, hydroxylamine derivs., hydroxamic acids, hydroxamic acid derivs. and aliphatic, cycloaliphatic, heterocyclic and aromatic cpds. which contain ≥ 1 N-hydroxy, oxime, N-oxy or N,N-dioxy function; (d) opt. ≥ 1 co-mediator selected from aryl-substd. alcohols, carbonyl cpds., aliphatic ethers, phenol ethers and alkenes; and (e) a small amt. of a free amine of one of the mediators used.
