Abstract

Procedimiento para la preparación de azina de la metiletilcetona en el que: a) se hacen reaccionar el amoniaco, el peróxido de hidrógeno y la metiletilcetona en presencia de una solución de trabajo, que comprende un sistema de activación constituido por una mezcla de una amida de ácido carboxílico y de la sal de amonio correspondiente para formar una azina; b) se separan la solución de trabajo y la azina, que contiene eventualmente la metiletilcetona que no ha reaccionado y butanol-2; c) se recicla la solución de trabajo hasta la etapa (a) después de un tratamiento eventual; d) se separan de la azina la metiletilcetona y el butanol-2; e) se purga una parte del butanol-2 de la corriente de la etapa (d) con el fin de mantener entre 0,05 y 0,15 la relación molar butanol-2 / MEK a la entrada de la etapa (a).
