ABSTRACT OF THE DISCLOSURE: A process for producing isopropyl alcohol and useful byproducts from cellulosic substrates without utilizing toxic acids. This process comprises the steps of: (1) digesting cellulosic substrates in a heated sodium carbonate substrates; (2) digesting the cellulosic product of step (1) in a heated solution of isopropyl alcohol an aluminium isopropylate to produce a glucose biomass and a black liquid of saturated acy- lic hydrogen carbon; (3) mixing the glucose biomass of step (2) under heat and pressure with basic aluminate plus amylo- lytic enzymes or xylophages bacteria to initiale fermentation of the glucose biomass; and (4) adding sodium acetate, calcium carbonate, the black liquid and a formol-phenol sulfonate solution of ROCH2-CH2-OH, ArOCH2-CH2-OH and RSCH2-CH2OH to the mixture of step (3) and progressively increasing the tempera- ture of such mixture to at least approximately 145 degrees and maintaining such temperature until isopropyl alcohol is produced.
