Patent ID: 8889891

Claim:
A method of preparing a furfuranol-based compound and a 2-furancarboxylic acid-based compound, comprising: reacting a furfural-based compound represented by Chemical Formula 1 below with a hydroxide of an alkali metal or an alkaline earth metal using an ionic liquid as a solvent, thus obtaining a furfuranol-based compound represented by Chemical Formula 2 below and a 2-furancarboxylic acid-based compound represented by Chemical Formula 3 below, wherein, R 1 is independently a valence bond, a C 1-10 alkylene group, a C 3-14 cycloalkylene group, a C 6-14 arylene group, a C 6-14 alkylarylene group or a C 6-14 arylalkylene group, and R 2 is independently a hydrogen atom, a C 1-10 alkyl group, a C 3-14 cycloalkyl group, a C 6-14 aryl group, a C 6-14 alkylaryl group or a C 6-14 arylalkyl group.
