A method for increasing the yield of alcohols by a Guerbet reaction in a gas phase and reducing production cost is provided. A method for producing alcohols by a Guerbet reaction, wherein the reaction is performed in a gas phase and at a total pressure of less than 1 atm and preferably from 0.01 to 0.5 atm, using one or more raw material alcohols.

Method for producing alcohol by guerbet reaction

The present invention is to provide a novel method for manufacturing various organic compounds from two or more kinds of alcohol, or one kind of alcohol having three or more carbon atoms. It is a method for synthesizing one kind of, or two or more kinds of organic compounds comprising allowing two or more kinds of alcohol or one kind of alcohol having three or more carbon atoms to contact a calcium phosphate catalyst such as hydroxyapatite, or hydrotalcite.

Method of synthesizing chemical industry raw materials and fuel compositions

The present invention is to provide compositions comprising organic compounds useful as a chemical industrial material or a fuel composition with the use of an alcohol such as ethanol as a material. It is a method for producing compositions using alcohol as a starting material and comprising: allowing alcohol to contact with an alcohol conversion catalyst such as hydroxyapatite (first step) and conducting a hydrogenation reaction respectively for all reaction products consisting of a liquid phase including alcohols, water and hydrocarbons of 4-12 carbons and a gas phase which is light gas containing paraffins, alcohols and olefins; all liquid phase reaction products consisting of all reaction products from which light gas has been removed; a liquid phase dehydration reaction products consisting of all reaction products from which light gas, unreacted alcohol and product water have been removed; and light gas (second step).

Method for producing composition using alcohol as starting material

The present invention provides a production method with which high molecular alcohols having an even number of carbon atoms such as 1-butanol, hexanol, octanol and decanol, and a mixture of these are efficiently collected through clean processes with the use of ethanol as a raw material. High molecular alcohols are produced from ethanol by using calcium phosphate-based compounds such as hydroxyapatite Ca(PO)(OH), tricalcium phosphate Ca(PO), calcium monohydrogen phosphate CaHPO.(0&#x2dc;2)HO, calcium diphosphate CaPO, octacalcium phosphate CaH(PO).5HO, tetracalcium phosphate Ca(PO)O or amorphous calcium phosphate Ca(PO). nHO as a catalyst, using ethanol as a starting material, and setting a contact time at 0.4 second or longer.

Method of synthesizing higher-molecular alcohol

A soft magnetic member which is formed by a composite of an organic object to satisfy a predetermined relationship with an antenna area, a circumference length, and a magnetic transmission ratio and a conductive member are provided between an antenna coil which is formed by at least one loop and a metal surface of the conductive member such as a metal casing. The magnetic flux which invades into the conductive object is blocked by the soft magnetic member and the conductive member so as to restrict the influence thereof.

Antenna for reader/writer and reader/writer having the antenna

An antenna coil includes an air-core coil wound helically in a plane and a plate magnetic core member inserted in the air-core coil to be approximately parallel with a plane of the air-core coil. The magnetic core member is formed by a soft magnetic metal, an amorphous or ferrite, or a composite member of a powder, flake and plastic, or rubber. The magnetic core member is formed by performing an injection molding operation or a compressing molding operation of the composite member. Alternatively, the magnetic core member is a magnetic coating formed by applying and drying the composite member. A non-magnetic conductive plate that has a conductivity is layered on a surface of the air-core coil through which the magnetic core member is inserted. The conductive plate is made of a copper, a copper alloy, an aluminum or an aluminum alloy having 0.01 to 2 mm thickness. The antenna coil is operated by relatively high frequency while it is rigid relatively.

A theftproof tag which is effective regardless of the material of the article to which it is attached. There is neither a change in resonance of a resonance circuit nor a decrease in the Q value due to the material of the surface of a theft monitored article, thereby decreasing errors in the operation of a theft monitor. The theftproof tag has a resonance circuit resonating to an electric wave at a specified frequency transmitted from a transmitting antenna, and having a coil unit and a capacitor electrically connected to both ends of the coil unit. The coil unit has a magnetic core member made of a composite material composed of a powder or flakes of a soft magnetic metal, and a plastic, and a winding wound around the periphery of the magnetic core member and connected to the capacitor, a portion of the magnetic core member facing the attaching surface of the article.
