PROCESS FOR PRESERVATION OF CELLULOSIC MATERIALS

摘要

Process for conservation of a cellulosic material, comprising a treatment wherein said cellulosic material is contacted with a stabilising agent, and at least one of the cellulosic material or the stabilising agent is cooled before and/or during the treatment. A deacidification agent comprising magnesiumdipropoxycarbonate, propanol and an HFC selected from HFC-134a and HFC-227ea is particularly preferred as stabilising agent.
