Patent ID: 8044120

Claim:
A process for obtaining at least one constituent of a lignocellulose material, wherein the constituent is solubilized selectively, or liberated selectively or solubilized and liberated selectively from a solubilized product of the lignocellulose material, and wherein at least one ionic liquid is employed for the solubilization and/or liberation, wherein the at least one ionic liquid is at least one ionic liquid represented by formula I wherein A together with the C—N group to which it is bonded, forms a 4- to 8-membered, saturated or unsaturated or aromatic ring, which is optionally substituted, which can optionally have further heteroatoms or heteroatom-containing groups, and which can have further fused-on saturated, unsaturated or aromatic carbocyclic rings or heterocyclic rings, B together with the amidino group to which it is bonded, forms a 4- to 8-membered, mono- or polyunsaturated, non-aromatic ring, which is optionally substituted and can have further fused-on saturated, unsaturated or aromatic carbocyclic rings or heterocyclic rings, R represents hydrogen or an organyl radical, Y n− represents a mono-, di-, tri- or tetravalent anion, and n represents one, two, three or four and at least one polymer solubilized therein.
