  • Process for washing a polysaccharide-based material which has been subjected to an oxidation
    Patent number: 9290583
    Abstract: The present invention relates to a process for washing a polysaccharide-based material which has been subjected to oxidation by at least one oxidizing agent, the said process comprising a first stage of washing with a first densified fluid which is inert with regard to the said oxidizing agent, characterized in that the first stage is followed by a second stage of washing with a washing composition comprising at least one second inert densified fluid and at least one alcohol. The said process according to the invention can additionally comprise a third stage of washing with a third inert densified fluid in order to remove the said alcohol deposited on the said polysaccharide-based material during the said second washing stage. Preferably, the said inert densified fluids are supercritical carbon dioxide.
