Preparation of optically active aliphatic carboxylic acids |
| abstract |
An improved process for the separation of enantiomers of a racemic mixture of certain aliphatic carboxylic acids or esters thereof is disclosed. The process involves adding a mixture of the aliphatic carboxylic acid to the material formed by: (i) forming a solution comprising said racemic mixture of a C 1 to C 6 linear or branched aliphatic carboxylic acid and an organic or inorganic solvent; (ii) treating said solution with a chiral organic nitrogenous base; (iii) precipitating from the reaction solution formed in step (ii) a crystalline material comprised of the less soluble diastereomeric salt. The solution is admixed with the crystalline material for a time sufficient to cause an increase in the amount of the less soluble diastereomeric salt in the crystalline material. |
