Abstract

Procedimiento para la recuperación de ciclohexanona-oxima a partir de una solución de la oxima en tolueno obtenida en la preparación de ciclohexanona-oxima a partir de ciclohexanona separando el tolueno y la oxima por destilación y recuperando la oxima sustancialmente pura, caracterizado porque la separación por destilación se comienza a partir de una solución de la oxima en tolueno obtenido por conversión incompleta de la ciclohexanona y que tienen un contenido de cilohexanona de más de 0,5 gramos por 100 gramos de oxima y se recupera la ciclohexanona-oxima con menos 0,1 gramos de cliclohexanona por 100 gramos de oxima.
