| titleOfInvention | Process for production of optically active organic carboxylic acid |
| abstract | Provided is a simple and easy process for the production of an optically active organic carboxylic acid. The simple and easy process comprises: either adding a specific amount of an alkali to an optically active enantiomer mixture which consists of enantiomers of an organic carboxylic acid and which has a difference between the molar proportions of the enantiomers, or neutralizing such a mixture with an alkali and adding a specific amount of an acid to the neutralized mixture; and then separating an organic carboxylic acid salt which is present in the mother liquor from an organic carboxylic acid which has been precipitated as a crystalline substance. The simple and easy process enables the production of an optically active organic carboxylic acid having an enhanced enantiomeric excess. Thus, the invention provides a simple and easy process for producing an optically active organic carboxylic acid having an enhanced enantiomeric excess from an optically active enantiomer mixture which consists of enantiomers of an organic carboxylic acid and which has a difference between the molar proportions of the enantiomers. |
