| Abstract：Synthesis of sorbitol by electro reduction from glucose was studied. Factors influenting the yield of sorbitol were current density, initial concentration of glucose, temperature and supporting electrolyte. The optimum conditions were determined. Current density was 0.176A/dm 2, temperature of reaction was 30℃, initial concentration of supporting electrolyte was 0.15mol/L the concentration of glucose was 0.106mol/L. Under these conditions, the cathode current efficiency of glucose was 86.84%. |
| Key words：glucose; sorbitol; electro reduction |
