Abstract

<p>La presente invención está relacionada con un método para la acetilación continua de elementos de madera. La acetilación se lleva a cabo con un medio de acetilación a una presión de al menos 1,5 barg en un medio ambiente de manera considerable libre de oxígeno. Alternativamente, el método de acuerdo con la invención comprende los pasos de: (a) alimentación de los elementos de madera en un reactor de acetilación continua en un medio ambiente de manera considerable libre de oxígeno, y (b) el tratamiento de los elementos de madera con un medio de acetilación en el reactor de acetilación continua a condiciones de reacción de acetilación de madera, a una presión de al menos 1,5 barg. El proceso de acuerdo con la presente invención permite acetilar elementos de madera a un alto contenido de acetilo en una forma muy eficiente, sin que se comprometa la calidad del material. Los elementos de madera acetilados pueden utilizarse en la producción de tablas de fibra de densidad media con calidad superior como estabilidad dimensional y durabilidad.</p>
