Abstract

UN NUEVO INTERMEDIO UTIL EN LA SINTESIS DEL ACIDO ETILENDIAMINOTRIACETICO (ED3A) O SUS SALES. EL ACIDO N,N''ETILENDIAMINODIACETICO (ED2AH2) O UNA SAL QUE CONTIENE HASTA UN EQUIVALENTE DE UN CATION BASICO SE CONDENSA CON UN FORMALDEHIDO PARA FORMAR UN INTERMEDIO CICLICO ESTABLE. LA ADICION DE CIANURO FORMA LA 1-CIANOMETIL-4-CARBOXIMETIL-3-CETO-PIPERAZINA O UNA SAL DE LA MISMA (MONONITRILO DE MONOACIDOS) QUE ES UN INTERMEDIO UTIL PARA LA PRODUCCION DE ED3A. EL NITRILO QUE SE ENCUENTRA EN LAS SOLUCIONES ACUOSAS SE PUEDE HIDROLIZAR PARA FORMAR ACIDO 2-OXO1,4-PIPERAZINODIACETICO (3KP) O SALES DEL MISMO. ANTE LA PRESENCIA DE UNA BASE EN EXCESO, SE FORMAN SALES DE ED4S QUE PRESENTAN UNAS PROPIEDADES Y UNA PUREZA EXCELENTES.
