Abstract
ESTA INVENCION SE REFIERE A UN PROCEDIMIENTO DE CINCO PASOS PARA PREPARAR UNA SAL DE METAL ALCALI PURIFICADO DE 4-SULFOFENIL[[](()1-OXIALCANOILO())AMINO[]]ALCANOATO EN UN RECIPIENTE DE REACCION SIN AISLAMIENTO DE INTERMEDIARIOS. EL PRIMER PASO ABARCA LA REACCION DE UNA SAL DE METAL ALCALI DE ACIDO 4HIDROXIBENCENOSULFONICO CON UN ANHIDRIDO CARBOXILICO C{SUB,2} A C{SUB,4} EN UN SOLVENTE PARA FORMAR UNA SAL DE METAL ALCALI DE ACIDO 4-ACILOXIBENCENOSULFONICO Y UN ACIDO CARBOXILICO C{SUB,2} A C{SUB,4}. EL SEGUNDO PASO ABARCA LA ADICION DE UN ACIDO [[](()1-OXIALCANOILO())AMINO[]]ALCANOICO Y UN CATALIZADOR DE TRANSESTERIFICACION AL PRODUCTO DE REACCION DEL PASO (A) Y CALENTARLO A UNA TEMPERATURA Y PRESION SUFICIENTE PARA MANTENER UN REFLUJO DEL SOLVENTE Y ELIMINAR EL ACIDO CARBOXILICO C{SUB,2} A C{SUB,4} DEL RECIPIENTE DE REACCION PARA FORMAR UNA MEZCLA DE REACCION QUE CONTENGA UNA SAL DE METAL ALCALI DE 4-SULFOFENIL[[](()1-OXIALCANOILO())AMINO[]]ALCANOATO. EL TERCER PASO ABARCA LA ELIMINACION DESOLVENTE DE LA MEZCLA DE REACCION FORMADA EN EL PASO (B). EL CUARTO PASO ABARCA EL MEZCLADO DE LA SAL DE METAL ALCALI DEL PRODUCTO DE 4-SULFOFENIL-[[](()1OXIALCANOILO())AMINO[]]ALCANOATO DEL PASO (C) CON ACIDO ACETICO. EL QUINTO PASO ABARCA LA SEPARACION DEL PRODUCTO DEL ACIDO ACETICO. LA SAL DE METAL ALCALI PURIFICADO DEL PRODUCTO DE 4SULFOFENIL-[[](()1-OXIALCANOILO())AMINO[]]ALCANOATO ES UTIL COMO UN ACTIVADOR BLANQUEANTE EN DETERGENTES.
