Abstract
Este proceso se refiere al control de la formación de acetales cuando se elimina el acetaldehído de un proceso de carbonilación de metanol mediante una columna de destilación extractiva. Los acetales se pueden formar mediante una reacción secundaria de acetaldehído y un alcohol (tal como metanol). El proceso controla las formaciones para evitar la acumulación excesiva de acetal en la corriente inferior de la columna de destilación extractiva.
