Abstract

Proceso de nitración de metil 2-furil cetona para producir metil 5-nitro-2-furil cetona, que incluye el tratamiento de la metil 2-furil cetona con una mezcla nitradora formada por ácido nítrico y anhídrido acético para formar un intermedio de nitración, caracterizado dicho proceso porque la fase de convertir el intermedio de nitración en metil 5-nitro-2-furil cetona comprende el tratamiento de dicho intermedio de nitración con una sal de una base fuerte bajo condiciones anhidras.
