Abstract: The object is to provide a method for producing a cyclic oligosaccharide through which a cyclic oligosaccharide can be efficiently synthesized. In addition, the object is to provide a novel cyclic oligosaccharide obtained through the production method. The method for producing a cyclic oligosaccharide includes subjecting a linear oligosaccharide, in which 5 to 10 α-glucosamines or derivatives thereof are bonded in series via 1,4-bonds, to a liquid phase electrolysis reaction.

Abstract: An electrolytic reactor comprises at least one electrolytic cell with an anode compartment and a cathode compartment separated by a separator, in particular a semipermeable membrane. The anode compartment comprises an inlet and an outlet for anolyte at opposed ends, said inlet and outlet being connected with each other via an anolyte circulation pipe equipped with a storage means for anolyte, an anolyte vessel and at least one adsorption filter for adsorbing molecular impurities. When molecular impurities comes from the cathode compartment through the separator, the electrolytic reactor acts also as a cleaning device for the catholyte.

Abstract: A catalyst-free electrochemical deuteration method using deuterium oxide as a deuterium source, adding an electrolyte, an organic compound containing an ethylenic bond or acetylenic bond, deuterium oxide, and an organic solvent into a reactor, applying a direct current voltage of 4-8 V between electrodes of a carbon felt in an atmosphere of an inert gas for an electrolytic reaction, to obtain a product, and purifying the product to obtain a deuterated product. In the method provided by the present disclosure, with the organic compound containing an ethylenic bond or acetylenic bond as a raw material, deuterium oxide as a deuterium source, cheap and readily available carbon electrode materials as cathodes and anodes, it is possible to obtain deuterated products by a direct current electrolysis in an organic solvent, without any transition metal catalysts.
