Acidic papers, books, and other sheets of cellulosic material may be deacidified and so given a prolonged life by bringing the papers, books, or other sheets of cellulosic material to be treated in intimate contact with a source of solid alkali such as calcium carbonate filled paper, at an elevated humidity and under mechanical pressure for a period long enough to produce deacidification; the process differs from other processes in that it is carried out in the solid state without the use of liquid or gaseous reactants.

Des papiers, des livres acides et d'autres feuilles de matériel cellulosique acides peuvent être désacidifiés et, ainsi, leur durée de vie peut être prolongée. Le procédé consiste à traiter les papiers, les livres et les autres feuilles de matériel cellulosique en les mettant en contact étroit avec une source d'alcali solide comme du papier chargé de carbonate de calcium, à une humidité élevée et sous pression mécanique pendant une période suffisamment longue pour entraîner la désacidification. Il diffère des autres procédés par le fait qu'il soit réalisé en milieu solide sans utilisation de réactifs liquides ni gazeux.
