Abstract
Procedimiento de preparación de alfa-aminoamidascaracterizado porque se prepara in situ un alfa-aminonitriloporque se efectúa una hidrólisis catalítica química de este último por reacción en solución acuosa de por lo menos un derivado carbonilado sobre dicho alfa-aminonitrilo en presencia de iones hidróxidos introducidos en pequeña cantidad en el medio de reacciónpreferentemente a razón de 005 a 03 moles de hidróxido por mol de alfta-aminonitrilo formadoy porque se extrae la alfa-aminoamida correspondiente obtenida.
