A new methed of electrolytic preparation of pure sugar solution which had already been reported by Jun MIZUGUCHI [J. Pzarm. Soc. Japan, 70, 494_??_519 (1950)] was applied to the preparation of xylose from peanut shells. The saccharified solution obtained by a new saccharification process (0.8 N HClO4, 97_??_100°, 6 hrs.) was submitted to the electrolysis in the cathode chamber of the diaphragm cell. Then ClO4, - and furfural ccntained in the saccharified solution were removed through electrolysis, aid HC1O4 was recovered as anolyte. Thus the saccharified solution was deacidified (pH 4) and refined at the same time by this electrolytic process. This refined solution was evaporated under reduced pressure to syrup, from which was solidified the crystalline mass giving a mp. of 98_??_104° with the yield of 13%. A more pure xylose was obtained by washing with acetic acid; giving a mp. 140_??_144°, furfural value 102%, and reducing value 98%, with the yield of 3.4%.
