Abstract
Procedimiento para la despolimerización de la celulosa, catalizada con un ácido, en el que se trata mecánicamente un material celulósico en presencia de cantidades catalíticamente suficiente de un ácido inorgánico y/u orgánico, en el que antes del tratamiento mecánico se trata la celulosa con una mezcla del ácido y un disolvente y se elimina el disolvente antes del tratamiento mecánico, dicho tratamiento mecánico es una molienda, en la que el material a moler se tritura empleando elementos de molienda.
