Paper Title:
Deacidification of Paper in Supercritical Carbon Dioxide (CO2SCF) Solvent System with Magnesium Acetate and Calcium Hydroxide
  Abstract

Alkali agents such as magnesium acetate and calcium hydroxide were used for deacidification of aged acidic papers by supercritical carbon dioxide and immersion treatment. In supercritical fluids, the alkali agent can be better combined with the cellulose fibers, and causing similar pH values as immersion; but the mechanical properties of paper will be a biggish increase. According to artificial aging tests, we find the CO2SCF treatment shows better than the immersion one, which would be related to the high level of alkali reserves.
