Abstract
Desacidificación de material celulósico. Se presenta en la patente que se solicita un producto para la desacidificación de materiales celulósicos alterados por la acidez, como papel, libros, documentos, prensa, guardados en bibliotecas, archivos y hemerotecas, que está formado por el propilato de magnesio carbonatado. Se emplea como disolvente el propanol en n- dipropilato de magnesio carbonatado y como vehiculante y diluyente en hidrofluorocarburo. El producto de desacidificación de esta patente de invención puede ser aplicado por rociado a través de boquillas, o por inmersión del material celulósico en el producto de desacidificación en la máquina correspondiente.
