d-Glucose was reduced by aluminium-nickel alloy in aqueous sodium hydroxide solution. 15_??_20% sodium hydroxide solution was allowed to drop slowly into the 8% d-glucose solution with suspension of aluminium-nickel alloy powder at 80°_??_90° with stirring. While aluminium is issolved by sodium hydroxide, hydrogen gas develops and the Raney nickel is prepared. By this ydrogen and the Raney nickel, d-glucose was spent completely and the yield of d-sorbitol was bout 80%, which was calculated from the amount of benzalsorbitol obtained.
