SACCHARIFICATION OF CELLULOSE

摘要

A method for effecting saccharification of raw cellulosic material taken from any available source. The cellulosic material is hydrolyzed by immersing it in a bath of anhydrous liquid hydrogen chloride to yield usuable glucose and other products. The cellulosic material may be processed through one or more pre-treatment steps. each acting to enhance the yield of glucose and other products when the pre-treated material is subjected to hydrolyzation by anhydrous liquid hydrogen chloride. The raw material may first be immersed in a catistic 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 another or second preparatory step, the material may be further prepared by subjecting it to a viscose process to produce a viscous solution of sodium cellulose xanthate in sodium hydroxide, from which solution the aqueous phase is separated, leaving a viscose intermediate. In the final step, the viscose intermediate is hydrolyzed by immersing it in a bath of anhydrous liquid hydrogen chloride.
