Abstract
PROPORCIONAR PROCESOS ADECUADOS PARA PRODUCCION INDUSTRIAL, MEDIANTE LOS CUALES PUEDEN PREPARARSE AMINOACIDOS N DE CADENA LARGA) Y SAL DE LOS MISMOS, PARTIENDO DE MATERIAS PRIMAS ECONOMICAS. UN ESTER ALQUILO DE UN ACIDO GRASO (2) REACCIONA CON UN AMINONITRILO (3), EN PESENCIA DE UN CATALIZADOR BASICO, PARA FORMAR UN AMIDONITRILO (1), EL AMIDONITRILO (1) SE HIDROLIZA EN UNA SAL (4) AMINOACIDA DE N RGA), EN PRESENCIA DE UNA SUSTANCIA BASICA, SE AJUSTA EL PH DE LA SOLUCION ACUOSA RESULTANTE A UN PH ENTRE 1 Y 5, CON UN ACIDO MINERAL, PARA OBTENER UN AMINOACIDO (5) DE N NA LARGA), Y SE RECUPERA ESTE AMINOACIDO. EN LAS FORMULAS, R1CO TOMOS DE CARBONO; R2 REPRESENTA UN ATOMO DE HIDROGENO O UN GRUPO ALQUILO, TENIENDO DE 1 A 3 ATOMOS DE CARBONO; R3 REPRESENTA UN GRUPO ALQUILENO, TENIENDO DE 1 A 5 ATOMOS DE CARBONO; R4 REPRESENTA UN GRUPO ALQUILO, TENIENDO DE 1 A 4 ATOMOS DE CARBONO; Y M REPRESENTA UN CATION MONOVALENTE.
