    Abstract: PURPOSE:To obtain a catalyst with high activity and high selectivity for reducing a carbonyl compound by supporting a catalyst compsn. specified in its atomic ratio on a carrier selected from oxides and hydroxides of aluminum, silicon, titanium or the like, zeolite, and silica-alumina. CONSTITUTION:At least one kind of a carrier selected from a group consisting of oxides and hydroxides of aluminum, silicon, titanium, zirconium, magnesium and iron, zeolite and silica-alumina is suspended in an aqueous medium to be reacted with a water-soluble copper salt and a water-soluble iron salt to precipitate copper and iron compounds on the carrier. Subsequently, a water-soluble aluminum salt is reacted with the copper and iron compounds to precipitate an aluminum compound. This precipitate is mixed with alkali metal to be baked to produce a catalyst wherein the atomic ratio of Cu Fe/A/(alkali metal and/or alkaline earth metal)/Zn is 1/0.4-2.5/0.5-5.0/0-0.4/0-1.0 is produced.

    Abstract: PURPOSE:To obtain a dehydrogenating catalyst having high activity and selectivity by using a carrier selected from oxides and hydroxides of aluminum, silicon, titanium, zirconium, magnesium and iron, zeolite and silica-alumina and specifying the atomic ratio of the catalyst. CONSTITUTION:A carrier is selected from a group consisting of oxides and hydroxides of aluminum, silicon, titanium, zirconium, magnesium and iron, zeolite and silica-alumina and the atomic ratio of Cu/Fe/Al/(alkali metal and/or alkaline earth metal)/Zr of a catalyst is specified to 1/0.4-2.5/0.5-5.0/0-0.4/0-1.0. In this case, when a substance containing an aluminum atom is used as a carrier, the atomic ratio of the whole of the catalyst including the carrier is calculated. The carrier is suspended in a water-soluble medium to be reacted with a copper salt and an iron salt and, subsequently, water-soluble aluminum is reacted with the reaction solution and an alkali metal salt is mixed with the formed precipitate and the resulting mixture is baked.

    Abstract: PURPOSE:To perform the reaction in the presence of a solvent soluble in a primary alcohol but insoluble in water under a condition that both the solvents and the produced water are distilled outside, when the primary alcohol or its mixture with any other compound are subjected to a dehydrative condensation reaction to provide a branched dimerized alcohol. CONSTITUTION:When a compound of formula I (R is straight chain or branched chain 1-6C alkyl, alkenyl) and a compound of formula II (R is straight chain or branched 1-22C alkyl, alkenyl, cycloalkyl, phenylalkyl) are condensed with each other in the presence of an alkaline substance (e.g. KOH) and, if necessary, a dehydrogenation catalyst (e.g. Pt-C) to provide the subject substance, the reaction is carried out in the presence of a solvent soluble in a primary alcohol and slightly soluble in water at 150-280 deg.C while refluxing the alcohols and the solvent and distilling the produced water outside. The solvent is preferably a hydrocarbon (e.g. benzene) having a boiling point of 75-200 deg.C.

Thereby, a copper-iron-Al catalyst having high activity and high selectivity can be obtd., and with this catalyst, high purity higher alcohol can easily be obtd.

    Abstract: PURPOSE:To obtain a copper-iron-aluminum-based hydrogenation catalyst having extremely high selectivity and high activity by using a carrier selected from silicon oxide, titanium oxide, zirconium oxide, etc., and specifying the atomic ratio. CONSTITUTION:A carrier is selected from silicon oxide, titanium oxide, zirconium oxide, magnesium oxide, iron oxide, and silica-alumina and is suspended in a water-soluble solvent. On the other hand, an alkali is reacted with a water- soluble copper salt and a water-soluble iron salt to precipitate a copper compound and an iron compound on the surface of the carrier. Then, an alkali and a water-soluble aluminum salt are reacted with a water-soluble aluminum salt to precipitate an aluminum compound on the surfaces of solid particles in the suspension. The precipitates are collected, washed with water, dried, and calcined. In this way, a copper-iron-aluminum-based catalyst having a composition with an atomic ratio of Cu/Fe/Al/Zn within the range of 1/(0.4-2.5)/(0.5-5.0)/(0-1.0) is obtained.
