Abstract

L'invention concerne un produit sous forme soluble et composé dedi-n-propylate de carbonate de magnésium, de n-propanol et d'un diluant hydrofluorocarboné (HFC) sélectionné dans 1,1,1,2-tétrafluoroéthane (HFC 134a) et 1,1,1,2,3,3,3-heptafluoropropane (HFC 227). On peut obtenir le produit au moyen d'un procédé consistant àpréparer une solution de di-n-propylate de carbonate de magnésiumdans du n-propanol et diluer ladite solution par addition du diluant HFC. Le produit se prête à la désacidification de la matière cellulosique et permet de préserver des objets en matière cellulosique.
