グルコン酸石灰の電解的製造に関する研究 (第1報) 陰極兼冷却壁として金属材料を用うる試み

抄録

An attempt was made to improve the electrolytic method whereby calcium gluconate could be prepared in a minimum period. In order to make it possible to allow electrolysis by the maximum current concentration, cooling system must be sufficiently performing. However, these cooling systems were of glass or porcelain up to the present which did not give sufficient cooling.
In the present experiment, Pb, Cu, Ni, and Ag metals were used as the cooler wall which was utilized as the cathode in order to avoid rusting of these metals. Test electrolysis with various compositions of electrolytic media showed that those metals used, especially Ag, in contact with the media were hardly corroded. It was also shown that no difference in electric efficiency, yield of the product or its quality existed between these experimental products and those obtained with the usual carbon cathode. These have provided good data for the construction of commercial electrolytic cell.
