Abstract

Procedimiento de producción de cetonas o de aldehídos obtenidos por la condensación seguida de la deshidratación y de la hidrogenación de cetonas o de aldehídos en un reactor, caracterizado por que dicho procedimiento comprende al menos una etapa de eliminación parcial de agua efectuada por al menos un módulo de pervaporación membranaria, alimentado tangencialmente e instalado lateralmente a dicho reactor y que funciona en bucle, a fin de deshidratar parcialmente una fracción saliente del reactor y en reciclar el concentrado deshidratado en dicho reactor, de manera que la concentración de agua en la masa de reacción del reactor esté mantenida entre el 2 y el 4% en peso, y por que la cetona es la metil isobutil cetona o MIBK, obtenida a partir de la hidrogenación de acetona, o el butanal obtenido a partir de acetaldehído.
