Abstract
La presente se refiere a un procedimiento para la fabricación de acetato de etilo, que consiste en hacer reaccionar alcohol etílico con ácido acético en presencia de un catalizador ácido sólido y en separar simultáneamente los componentes de reacción por destilación en un dispositivo de destilación reactiva que comprende al menos tres zonas: una zona de reacción en la cual la reacción ocurre simultáneamente con la separación por destilación de los componentes en una zona de separación superior y en una zona de separación inferior, la fase orgánica obtenida en la zona de separación superior es aislada y dejada parcialmente en reflujo en la zona de reacción. El procedimiento de la presente mejora con respecto, primero, a los costos operativos de energía, mientras que al mismo tiempo se obtiene un grado de conversión de etanol totalmente satisfactorio, y segundo, una corriente de la cola de la columna contiene una muy baja proporción de ácido, lo cual simplifica el resto del procedimiento y reduce el costo de energía.This refers to a process for the manufacture of ethyl acetate, which consists in reacting ethyl alcohol with acetic acid in the presence of a solid acid catalyst and simultaneously separating the reaction components by distillation in a reactive distillation device comprising at least three zones: a reaction zone in which the reaction occurs simultaneously with the distillation separation of the components in an upper separation zone and in a lower separation zone, the organic phase obtained in the upper separation zone is isolated and partially refluxed in the reaction zone. The process of the present improvement with respect, first, to the energy operating costs, while at the same time a completely satisfactory degree of ethanol conversion is obtained, and second, a column tail current contains a very low proportion of acid, which simplifies the rest of the procedure and reduces the cost of energy.
