Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO DE SINTESIS DE AZINAS A PARTIR DEL AGUA OXIGENADA, DEL AMONIACO Y DE UN REACTIVO QUE LLEVA UN GRUPO CARBONILO CARACTERIZADO EN QUE SE PONE EN CONTACTO ESTE REACTIVO UNA AMIDA DE ACIDO DEBIL Y LA SAL DE AMONIO CORRESPONDIENTE A ESTE ACIDO Y A CONTINUACION SE SEPARA LA AZINA OBTENIDA. LA INVENCION SE REFIERE TAMBIEN A PROCESOS EN LOS QUE LA REACCION SE HACE EN PRESENCIA DE CUALQUIER MEZCLA QUE CONTIENE UNA AMIDA Y DESPUES SE RECUPERA LA AZINA Y EL RESTO DEL MEDIO DE REACCION SE TRATA PARA REGENERAR LA AMIDA.
