| titleOfInvention | OXIDATIVE BLEACHING OF CELLULOSE USING VANADIUM-SUBSTITUTED POLYOXOMETALATES. |
| abstract | A method for delignifying wood pulp and fiber is disclosed. The method comprises the steps of obtaining a wood pulp and exposing the wood pulp to a polyoxometalate of the formula [VlMomWnNboTap(TM)qXrOs]x- where l is 0-18, m is . 0-40, n is 0-40, o is 0-10, p is 0-10, q is 0-9, r is 0-6, TM is a d-electron-containing transition metal ion, and X is a heteroatom, which is a p or d block element, where l+m+n+o+p>/=4, l+m+q>0 and s is sufficiently large that x>0. The exposure is under conditions wherein the polyoxometalate is reduced. In a preferable form of the invention, the method additionally comprises the step of reoxidizing the polyoxometalate. |
