Abstract
L'INVENTION CONCERNE UN PROCEDE DE PURIFICATION D'ESTERS ALKYLIQUES INFERIEURS DE L'A-L-ASPARTYL-L-PHENYLALANINE. ON MET L'ESTER ALKYLIQUE INFERIEUR DE L'A-L-ASPARTYL-L-PHENYLALANINE EN CONTACT AVEC UNE RESINE ECHANGEUSE D'ANIONS DU TYPE CL DANS UN SOLVANT AQUEUX. LES IMPURETES SONT ALORS ADSORBEES PAR LA RESINE ECHANGEUSE D'ANIONS, ET L'ESTER ALKYLIQUE INFERIEUR DE L'A-L-ASPARTYL-L-PHENYLALANINE EST RECUPERE DANS UN ETAT PURIFIE. LES ESTERS ALKYLIQUES INFERIEURS DE L'A-L-ASPARTYL-L-PHENYLALANINE, EN PARTICULIER L'ESTER METHYLIQUE, SONT INTERESSANTS EN TANT QU'EDULCORANTS.
