Abstract: PROBLEM TO BE SOLVED: To provide the electrolysis, in which a solid polymer electrolyte technology is applied and the current density can be maintained in a constant value for a relatively long period of time without increasing cell voltage. SOLUTION: The electrochemical reaction is conducted in an electrolytic cell which has a solid electrolyte comprising one or more layers of ion exchange membranes superposed in the up-and-down direction and has a cathode and an anode which are brought into contact directly with the solid electrolyte, using an electrolytic solution, which is an organic solution substantially containing no electrically conductive salt, at the temp. of the boiling point of the electrolytic solution or a temp. lower by 0-5 deg.C than the boiling point.

Abstract: PROBLEM TO BE SOLVED: To decrease the production of the secondary product and to isolate a desired product from the reaction mixture at a low cost by using a solid electrolyte and an electrolytic liquid having a specified compsn. to carry out oxidation. SOLUTION: The solid electrolyte consists of a cation exchange membrane or lots of layers of the membranes. The electrolytic liquid is an org. soln. containing no supporting electrolyte and contains, by wt.%, 10 to 90% of methanol, 1 to 50% of a compd. selected from compds. expressed by formula I and formula II, 1 to 50% of 1-15C carboxamides which may be N-alkylated, and 0 to 30% of inert solvent. In the formulae I, II, R' independently represents hydrogen, 2-4C alkyl groups or the like, A independently represents methylene or the like, B independently represents H or O-CH3, m is 0 to 3, n is 1 to 3, X and Y are the same as A and B, respectively, but are selected in such a manner that the oxidation state of the compd. of formula II is lower by at least 1 than the oxidation state of the compd. of formula I.

Abstract: PROBLEM TO BE SOLVED: To provide a method for electrochemical methoxylation of a methine, methylene or methyl group of aliphatic or alicyclic mono-ether or di-ether. SOLUTION: The electrochemical methoxylation of a methine, methylene or methyl group present at α-position with respect to an ether-oxygen atom is conducted in an electrolytic cell, which has a solid electrolyte comprising a cation exchange membrane or several cation exchange membranes layered in the up-and-down direction and has a cathode and an anode which are brought into contact directly with the solid electrolyte, using, as an electrolytic solution, an organic solution containing, by weight, a) 10-90% methanol, b) 1-50% compound selected from starting ethers or methoxylated ethers and c) 0-30% other inert solvent and substantially containing no supporting electrolyte.

Abstract: PROBLEM TO BE SOLVED: To provide an electrolytic cell enabling the preparation of compounds with a high yield, selectivity and space time yield, which has a relatively simple structure compared to divided cells. SOLUTION: The electrolytic cell comprises two single electrodes and one or more bipolar electrodes positioned between them. One of the single electrodes, together with some of the bipolar electrodes that are charged identically to the single electrode, and forms a working electrode, and the other single electrode, together with some of the bipolar electrodes charged identically, forms a counter electrode. The space between the counter electrode and the working electrode is not divided. The surface of the counter electrode comprises electrochemically active or inactive parts, and the sum of the electrochemically active parts on the surface of the counter electrode is a few times smaller than the sum of the electrochemically active parts on the surface of the working electrode.

Abstract: PROBLEM TO BE SOLVED: To provide a method for electrochemically oxidizing at least one kind of organic compound by bringing the organic compound into contact with an anode. SOLUTION: The anode comprises a carrier of conductive material and a conductive anodically polarized layer formed on the carrier on the spot by deposition. By the method for oxidizing an organic compound, high space-time yield and high selectivity are attained, the oxidation of solvent is minimized, and the current density is increased.

Abstract: PROBLEM TO BE SOLVED: To enable the use adequate for reaction of an organic compound by coating an electrode with a diamond layer which is poreless. SOLUTION: The material of the substrate of the electrode is preferably one or more among carbide, silicide and boride. The substrate has preferably a core material or an intermediate layer applied on the core material. The core material may be made of graphite or Ti or Mo or Au or their combination. The intermediate layer may be formed of Au or Pt or their mixture. The boron content of the diamond layer is preferably specified to 10 to 2,000 ppm, more preferably 50 to 1,000 ppm. The electrode is produced by cleaning the surface of the substrate, then seeding the surface at a high diamond nucleus forming density and coating the surface with diamond. As a result, the formation of pores in the diamond layer may be prohibited.
