Process for the production of DL-serines |
| abstract |
Production of DL-serine by heating a strong acid type cation exchange resin having aziridine-2-carboxylic acid adsorbed thereto. Specifically, an industrial process for producing DL-serine is provided which comprises treating an a-halogeno-o-aminopropionitrile or its mineral acid salt in water or a water-containing organic solvent with an alkali or alkaline earth metal hydroxide to form an alkali or alkaline earth metal aziridine-2-carboxylate, treating the reaction mixture with a strong acid type cation exchange resin to cause adsorption of aziridine-2-carboxylic acid, and thereafter heating the cation-exchange resin. |
