Abstract

Se describen procesos economicos para la recuperacion y refinacion de compuestos organicos, valiosos que contienen nitrogeno, que se forman mediante la oxidacion catalitica de al menos un compuesto de alimentacion seleccionado del grupo que consiste de propano, propileno, isobutano e isobutileno en presencia de amoniaco para producir un efluente gaseoso. Los procesos de la invencion incluyen enfriar rapidamente el efluente gaseoso del reactor con un liquido acuoso para enfriamiento rapido; formar una solucion acuosa que comprende el mononitrilo insaturado, correspondiente, cianuro de hidrogeno y otros co-productos organicos; y utilizar una secuencia integrada de destilaciones y separaciones de fases para recuperar la recirculacion de un liquido acuoso, util y obtener productos deseados que contienen nitrogeno. De acuerdo con la invencion las soluciones acuosas son fraccionadas en un sistema integrado de columnas de multiples etapas mientras que una cantidad efectiva para inhibir la polimerizacion de al menos un miembro de una clase preseleccionada de compuestos de p-fenilendiamina se mantiene en el mismo.
