Zusammenfassung:	PURPOSE:To produce 2-furancarboxylic acid useful as an intermediate for pharmaceuticals, etc., from furfural or furfuryl alcohol without by-producing or leaving furfuryl alcohol which is a cause of discoloration. CONSTITUTION:2-Furancarboxylic acid is produced at a low cost by carrying out the oxidative dehydrogenation of (a) furfural or furfuryl alcohol in the presence of (b) an alkali metal hydroxide and/or an alkaline earth metal hydroxide, (c) water and (d) a copper-containing catalyst at =1 equivalent (preferably 1.0-2.0 equivalent) of (b), >=10wt.% (preferably 40-50wt.%) of (c) and preferably 5-50wt.% of (d) based on the raw material (a). In addition to the above-mentioned effects, the catalyst is easily separable and the separated catalyst is repeatedly usable and, accordingly, the process has economical advantage.
