    • Cellulose solution is provided to prepare the homogenous solution which can be manufactured at a low temperature less than 100°C to have high concentration by using the specific ionic liquid melting the cellulose. Cellulose solution is manufactured by dissolving the cellulose in the ionic liquid. The ionic liquid comprises a quaternary ammonium cation indicated as the chemical formula 1 and an anion indicated as the chemical formula 2. In the chemical formula 1, R1, R2, R3, R4, R5, R6, R7, and R8 are the same or different and are selected from C1-C6 alkyl group, C1-C6 alkylcarboxy acid group, C1-C6 alkylester, hydroxy C1-C6 alkyl group and C1-C6 alkoxy C1-C6 alkyl group, wherein the case that R1 and R2 are an alkyl group at the same time is excluded. In the chemical formula 2, R9 and R10 are selected from respectively hydrogen atom, C1-C6 alkyl group and hydroxy C1-C6 alkyl group.
