Abstract

SE PRESENTA UN NUEVO PROCESO PARA PREPARAR ACIDO DE MONOAMIDO ALTAMENTE PURO MEDIANTE LA REACCION DE UN ACIDO DIBASICO Y UN AMINO EN EL QUE UN MAYOR EXCESO MOLAR DE ACIDO DIBASICO SE UTILIZA Y SE RECUPERA DE FORMA CONVENIENTE PARA SU RECICLADO EN EL PROCESO PARA PREPARAR CANTIDADES ADICIONALES DE DICHO ACIDO DE MONOAMIDO. SE HA DESCUBIERTO QUE LA AMIDACION DE AMBOS GRUPOS ACIDOS DEL ACIDO DIBASICO SE MANTIENE EN NIVELES BAJOS MIENTRAS LA EFICIENCIA DE LA REACCION SE MANTIENE MEDIANTE EL RECICLADO DEL ACIDO INICIADOR QUE NO HAYA REACCIONADO. EL COMPUESTO DE DIAMIDO NO DESEADO SE SEPARA DEL PRODUCTO DESEADO MEDIANTE UN PRIMER PASO DE FORMACION DE UNA SAL SOLUBLE EN AGUA DEL ACIDO DE MONOAMIDO Y POSTERIORMENTE ELIMINANDOLA DEL SUBPRODUCTO DE DIAMIDO INSOLUBLE MEDIANTE MEDIOS CONVENCIONALES TALES COMO LA FILTRACION. EL ACIDO DE MONOAMIDO DESEADO PUEDE RECUPERARSE POR ACIDIFICACION DE LA SAL PRECIPITANDO DE ESTA FORMA EL ACIDO PARA SU FACIL RECUPERACION DE UN MEDIO ACUOSO.
