    摘要: A method of producing a phenol compound comprising a step of oxidizing an aromatic aldehyde to an aryl formate and an aromatic carboxylic acid with an oxygen-containing gas, and a step of decomposing the aryl formate to the phenol compound. To facilitate the separation of the aryl formate and the unreacted aromatic aldehyde, a mixture of the aryl formate and the unreacted aromatic aldehyde is recycled to the oxidation process to concentrate the aryl formate in the oxidation mixture. Alternatively, the oxidation process is carried out in an organic solvent having substantially no ability of dissolving water to increase the conversion of the aromatic aldehyde and the selectivity of the aryl formate, thereby producing the aryl formate in a high yield. In another method, the aryl formate is produced by oxidizing the aromatic aldehyde in the organic solvent having substantially no ability of dissolving water with performic acid generated in situ in the reaction system from the reaction between formic acid and hydrogen peroxide. Since the oxidation proceeds in the organic solvent, hydrogen peroxide in aqueous phase contact the aromatic aldehyde. This significantly reduces the amount of explosive cyclic perther and a high-boiling product.

    摘要: A catalyst for removal of carbon monoxide from a hydrogen-containing gas that contains carbon monoxide, is provided. The catalyst includes a metal oxide-containing carrier, and a ruthenium component and a lanthanide component both supported on said carrier. Carbon monoxide can be removed from the hydrogen-containing gas with methanation reactions suppressed over a wide temperature range by bringing the gas into contact with oxygen in the presence of said catalyst.

    摘要: In an order wire communication control method in a bidirectional line-switched ring network system, two line terminalends located at both sides of faulty location transmit failure occurrence information utilizing APS bytes of APS protocol to other line terminalend in response to occurrence of failure in an order wire communication path on the ring network. The line terminalend where the order wire is terminated is released from termination in response to reception of the failure occurrence information of the APS bytes. Then, one of two line terminalends at both sides of the faulty location, commands termination of the order wire for the line repeater located closest to the faulty location among a plurality of line repeaters under control thereof. Thus, after release from failure, terminating control of the order wire becomes unnecessary to make it possible for all of the line terminalend to perform order wire communication.
