Abstract

Innovative neutralizing and strengthening treatments for aged acidic paper have been developed, based on the use of supercritical carbon dioxide (CO2SCF) as solvent system. After treatment with the non toxic neutralizing agent CaCO3 in CO2SCF, acidic papers exhibited a pH increase of water extracts, the creation of an alkaline reserve and a decrease in the rate of artificial aging, while mechanical tensile properties of aged acidic papers improved after treatment with catechol both simply dissolved in ethanol or in CO2SCF in the presence of ethanol as co-solvent.
