In order to examine the industrial method for the manufacture of D-ribose, constant current electrolytic reduction of D-ribonolactone was carried out. It was found that the yield of D-ribose was increased by the use of the ammonium salts ((NH_4)_2SO_4,(NH_4)_2HPO_4,(NH_4)H_2PO_4,NH_4Cl, NH_4NO_3) in place of the alkali metal salts (Na_2SO_4,Li_2SO_4) hitherto used as the electrolyte in this kind of electrolysis. As a reason for this increased yield, an attempt was made to endorse the assumption based on the interfacial structure at the contact surface between the electrode and the electrolyte solution by a comparative experiment using ammonium sulfate and sodium sulfate as the electrolyte. It was also revealed that the addition of boric acid was effective to some extent in preventing the formation of D-ribitol.
