Abstract

Un producto de etanol crudo obtenido de la hidrogenación de ácido acético comprende etanol y acetato de etilo; utilizando una columna de destilación operada a una presión de 0.1 a 100 kPa, el acetato de etilo y el etanol pueden ser separados efectivamente; además, mantener la cantidad de agua que se alimenta a la columna de destilación a una cantidad de menos de 10% en peso, con base en el peso de todos los componentes alimentados a la columna de destilación, proporciona un beneficio de energía.
