Abstract

El producto se presenta en forma de una disolución y está compuesto por di-n-propilato de magnesio carbonatado, n-propanol, y un diluyente hidrofluorocarbonado (HFC) seleccionado entre 1,1,1,2-tetrafluoroetano (HFC 134a) y 1,1,1,2,3,3,3-heptafluoro-propano (HFC 227). El producto puede obtenerse mediante un procedimiento que comprende preparar una solución de di-n-propilato de magnesio carbonatado en n-propanol y diluir dicha solución por adición del diluyente HFC. El producto es adecuado para desacidificar material celulósico y preservar objetos a base de material celulósico.
