A method for producing urethane compounds includes allowing a primary amine, a urea and/or an N-unsubstituted carbamate, and an alcohol to react in the presence of a compound containing a noncoordinating anion and a metal atom as a catalyst.

An electrolyzer is comprised of an anode and a cathode which are in contact with an electrolytic solution, wherein at least one of the anode and the cathode is composed of an electric conductor having a gas permeable structure comprising a gas generating surface at which gas is generated by electrolysis of the electrolytic solution, a plurality of through holes leading from the gas generating surface to a different surface and allowing the gas generated on the gas generating surface to selectively pass therethrough, and a gas releasing surface which is the different surface for releasing the gas supplied from the gas generating surface via the through holes. At least one of a surface treatment which causes the gas generating surface to be lyophilic for the electrolytic solution and a surface treatment which causes the gas releasing surface to be lyophobic for the electrolytic solution is performed.

Electrolyzer, electrodes used therefor, and electrolysis method

A gas generating device of present invention is generated a first gas at a first carbon electrode by applying a voltage between said first carbon electrode and a second electrode to electrolyzing an electrolytic solution. The first carbon electrode is an anode or a cathode. The first carbon electrode is provided with a plurality of fine gas flow channels which selectively pass said first gas generated on one surface of said first carbon electrode to the other surface without allowing said electrolytic solution to permeate therethrough.
