Abstract
Official abstract text for this publication.
An ionic liquid represented by the following chemical formula, [(CH3)3N(CH2)2OH]+[NH2(CH2)3CH(NH2)COO]−, which provides an ionic liquid capable of dissolving cellulose within twenty-four hours.
First claim
Opening claim text (preview).
The invention claimed is: 1. A solution in which cellulose has been dissolved in an ionic liquid represented by the following chemical formula (I) [(CH 3 ) 3 N(CH 2 ) 2 OH] + [NH 2 (CH 2 ) 3 CH(NH 2 )COO] − (I). 2. The solution according to claim 1 , wherein the solution further contains water; and weight ratio of the water to the ionic liquid is not more than 4.3%. 3. The solution according to claim 1 , wherein the solution further contains an aprotic polar solvent. 4. The solution according to claim 3 , wherein the aprotic polar solvent is dimethyl sulfoxide. 5. The solution according to claim 4 , wherein weight ratio of the dimethyl sulfoxide to the ionic liquid is not more than 309%.
