  • Solvent system for polysaccharides
    Patent number: 4097666
    Abstract: Natural or modified polysaccharides are dissolved in a solvent system comprising dimethyl sulfoxide and formaldehyde. The solvent system is particularly suitable for dissolving cellulose due to the fact that cellulose is rapidly dissolved under moderate conditions of temperature and pressure. The dissolved polysaccharides are readily recovered from the solvent system by diluting the solvent system with water or a short chain alcohol.
