Method for producing alkali metal salt of L-ascorbic acid |
| abstract |
PROBLEM TO BE SOLVED: To provide a method for continuously producing an alkali metal salt of L-ascorbic acid at a low equipment cost without causing a decrease in yield. The following steps: a) 2-keto-L-gluconic acid or diacetone-2-keto-L-gluconic acid is converted to C 1. Esterification with -C 10 -alcohol in the presence of an acid catalyst, b) the 2-keto-L-gluconic acid-C 1 formed -C 10 - alkyl esters of C 1 -C 10 - comprising the step of rearrangement in the presence of an alkali metal alcoholate, in the case of the preparation of alkali metal salts of L- ascorbic acid, the process steps a) and b) sequentially Implemented |
