Abstract
Un método de purificacion de ácido acético que contiene impurezas de terpeno y terpenoide, incluye: a) el suministro de ácido acético que contiene impurezas de terpeno y terpenoide y agua a una columna de destilacion; b) la remocion azeotropica de impurezas de terpeno y terpenoide de la mezcla de ácido acético y agua suministrada a la columna como destilado y c) la remocion de una corriente de producto de la columna que contiene ácido acético purificado de las impurezas de terpeno y terpenoide. El método es particularmente efectivo para purificar ácido acético recuperado a partir de un proceso de purificacion de madera.
