Saccharification of cellulose

Abstract: A method for effecting saccharification of raw cellulosic material taken from any available source. In the first step, the raw material is immersed in a caustic solution which swells the cellular structure to render it more reactive and acts to solubilize the lignins and other compounds contained therein, these being washed away to provide a prepared cellulosic material. In the second step, the prepared material is subjected to a viscose process to produce a viscous solution of sodium cellulose xanthate in sodium hydroxide, from which solution the aqueous phase is separated to provide a viscose intermediate. In the final step, the viscose intermediate is hydrolyzed by immersing it in a bath of anhydrous liquid hydrogen chloride to yield usable glucose and other products.
