US Patent:
5554791, Sep 10, 1996
Filed:
Jul 11, 1994
Appl. No.:
8/272456

Assignee:
Albemarle Corporation - Richmond VA
International Classification:
C07C22900
US Classification:
562565
Abstract:
This invention relates to a process for selectively producing and recovering [S,S]-ethylenediamine-N,N'-disuccinic acid by the reaction of L-aspartic acid and 1,2-dihaloethane in an aqueous medium, wherein a stoichiometric deficiency of 1,2-dihaloethane is used and wherein the resultant aqueous solution obtained from the reaction is co-fed to water with a mineral acid to preferentially precipitate out [S,S]-ethylenediamine-N,N'-disuccinic acid from the solution.
