| titleOfInvention | Process for preparing dl-serine and process for separation and purification of the same |
| abstract | Disclosed is a process for preparing DL-serine, which ncomprises synthesizing DL-serine according to Strecker nreaction with use of a cyan compound, ammonium chloride, nammonia and a reaction substrate comprising glycol naldehyde, nwherein the Strecker reaction is carried out under the nreaction conditions of: nmolar ratios of the starting materials of: nglycol aldehyde/cyan compound: more than 1.0 and not nmore than 1.50 nammonium chloride/glycol aldehyde: more than 1.0 and nnot more than 2.0 nammonium/cyan compound: 1.0 to 7.0 nreaction temperature: 20 to 80 °C nreaction time: 15 to 120 minutes, nand the reaction product obtained is hydrolyzed. nDisclosed is also a process for separation and purification nof DL-serine produced in the above by subjecting the naqueous solution containing DL-serine alkali salt obtained nto ion exclusion chromatography by use of a strongly acidic ncation exchange resin, neutralizing the fractionated DL-nserine fractions to near the isoelectric point of DL-serine nand subjecting the neutralized product to ion exclusion nchromatography with a strongly acidic cation exchange nresin. |
