Mass Deacidification - Current Services

Current Services

There are several commercial deacidification techniques currently on the market.

• The BookKeeper process is a non-aqueous, liquid phase process that uses magnesium oxide. BookKeeper is available through Preservation Technologies, L.P. with plants in the U.S., Spain, Japan, Poland, The Netherlands, and South Africa.

• The CSC Book Saver uses carbonated magnesium propylate for deacidification. It is available through Conservación de Sustratos Celulósicos S.L. (CSC) (Barcelona, Spain).

• The Papersave process was developed by Battelle Ingenieurtechnik GmbH and is, therefore, sometimes referred to as "the Battelle Process". The process uses magnesium titanium alkoxide. It is available in Europe through Nitrochemie Wimmis (Wimmis, Switzerland) under the name of Papersave Swiss and the Zentrum für Bucherhaltung (Leipzig, Germany).

• The Wei T'o process uses methoxy magnesium methyl carbonate, or isopropoxy magnesium isopropyl carbonate, and new products are coming out in 2008. Wei T'o is less commonly used for mass deacidification treatment than for single item deacidification. Wei T'o products are available through Wei T'o Associates Inc.(Matteson, USA).

BookKeeper, CSC Booksaver, Papersave and Wei T'o are also available as a hand held sprays.
