Producing (s,s)-alkylenediamine-n,n'-disuccinic acid |
| abstract |
A method for producing (S,S)-alkylenediamine-N,N'-disuccinic acid, comprises allowing ammonium L-aspartate to contact with an alkali metal hydroxide compound, removing ammonia and then allowing the resulting compound to react with a dihaloalkane, wherein concentration of residual ammonia in an aqueous medium after the removal of ammonia is 4.0% by weight or less of the aspartic acid-based amount of the aspartic acid salt in the aqueous medium. The present method does not spoil the product quality, is inexpensive and efficient and can be practically used industrially. |
