Abstract

Se divulga un método de purificación del fluido de acetilación utilizado recuperado a partir de un proceso de acetilación de madera. El método involucra someter el fluido de acetilación recuperado a cristalización por enfriamiento. Mediante este método se eliminan las impurezas de terpenos y terpenoides, así como otras impurezas. También se describe un método para acetilar madera que da como resultado madera acetilada y fluido de acetilación utilizado que comprende ácido acético, y purificación del fluido de acetilación utilizado mediante cristalización por enfriamiento.
