ABSTRACT:
The invention relates to a process for producing essentially pure cellulose granules which comprises treating finely-divided particles of essentially pure cellulose in aqueous suspension with an agglutinating reagent which promotes agglutination of said particles, causing said particles to agglutinate, and mechanically separating the agglutinated cellulose particles from the suspension medium leaving a wet mass of agglutinates, washing said wet mass with water until said agglutinating reagent has been removed therefrom, leaving a second wet mass consisting essentially of agglutinated cellulose particles and water, and displacing the water with a solvent which is solvent for water but non-solvent for cellulose, and removing the water from said second wet mass by a non-evaporative procedure wherein coalescence of said agglutinated particles is prevented and said agglutinated particles dry into discrete granules of essentially pure cellulose.
