A method for producing L-ascorbic acid which comprises (a) forming a substantially anhydrous slurry of 2-keto-l-gulonic acid and a surfactant in a supporting organic layer, and (b) reacting said slurry with a substantially anhydrous acid catalyst to convert said 2-keto-l-gulonic acid to L-ascorbic acid. L-ascorbic acid is produced in relatively high yields in a relatively short period of time by converting 2-keto-l-gulonic acid to L-ascorbic acid by acid catalysis of 2-keto-l-gulonic acid under substantially anhydrous conditions. |
