| titleOfInvention | Method for producing N-acetyl-D, L-α-aminocarboxylic acid |
| abstract | (57) [Summary]nN from the corresponding D, L-α-aminocarboxylic acid by acetylation in acetic acid using acetic anhydride and isolation of the resulting N-acetyl-D, L-α-aminocarboxylic acid from the acetylated mixture. In the known acetylation process for the production of -acetyl-D, L-α-aminocarboxylic acid, a large amount of salt is inevitably produced, or N-acetylated α-amino acid of sufficient purity is obtained. Requires a treatment using water. Acetylation is carried out at 60-150 ° C. at a concentration of less than 3 mol of α-aminocarboxylic acid per liter of acetic acid, the concentration being at standard conditions of pressure and temperature and N-acetyl- By obtaining D, L-α-aminocarboxylic acid as a melt or a solid by evaporation and concentration, the treatment of N-acetyl-D, L-α-aminocarboxylic acid with water can be completely eliminated. Nevertheless, high quality and yields and also purity are obtained. N-acetyl-D, L-α-aminocarboxylic acid used for enzymatic resolution in a method for producing an optically active α-aminocarboxylic acid. |
