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.
摘要:
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).

摘要:
It is intended to provide a remineralization promoter for tooth enamel and a composition for an oral cavity, which can highly effectively promote the remineralization of tooth enamel and strongly inhibit dental caries. The remineralization promoter for tooth enamel and the composition for an oral cavity are characterized by containing amorphous hydroxyapatite and/or amorphized hydroxyapatite showing two peaks at 2θ=31 to 35° in X-ray diffraction. The amorphized hydroxyapatite is obtained by reacting calcium salt with phosphate in an aqueous solution and drying the reaction solution at a temperature of 10 to 70° C.
