    摘要: A hydrogenation reaction catalyst precursor of the present invention comprises a catalyst carrier (A) and a metal oxide composition (B) carried on or mixed with the catalyst carrier (A) at a weight ratio of (B)/(A)=15/85 to 65/35; the catalyst carrier (A) comprising a carrier base material of silica, etc. and a coating of titanium oxide and/or titanium hydroxide, the metal oxide composition (B) comprising copper oxide, zinc oxide, and at least one oxide of a metal selected from the group consisting of an element of group IIa of the periodic table, an element of group IIIb of the table, a lanthanide element, and an actinide element at a weight ratio of 100/(0 to 25)/(0 to 25). A hydrogenation reaction catalyst with a high catalytic activity and a high reaction selectivity is obtained by reduction of the hydrogenation reaction catalyst precursor. By the use of the hydrogenation reaction catalyst of the present invention, a high quality alcohol can be produced at a high yield and with a high selectivity even at a low reaction temperature and a low hydrogen pressure.

    摘要: A stable creosote product is prepared from which little or no sludge heel settles and which does not require heat to be applied to prevent settling out of solids. The stable product is obtained by a method that mechanically reduces the particle size or the salts that form upon cooling below the limpid point. The layer of salt which settles on the bottom of the beaker is then mechanically broken and homogenized. The fine salts which had previously settled and were homogenized, did not resettle but remained relatively evenly dispersed throughout the mixture and remained dispersed even after prolonged periods of uninterrupted standing. The salts are not allowed to settle before homogenizing. Little or no heel formation was detected in the creosote in which the settled and material was homogenized as described.

    摘要: This invention pertains to a process for preparing hydroxy mononuclear aromatic compounds by reacting an alkali metal hydroxide with a mononuclear aromatic compound, e.g., benzene, xylene or toluene. The reaction is carried out in the presence of a metallic hydrogenation catalyst, suitably copper, nickel, rhodium or cobalt, the metal being present in an amount sufficient for catalyzing the reaction. The hydroxy mononuclear aromatic compound is then formed by adding a protonating agent to the resulting reaction product, with the protonating agent liberating the hydroxy compound from the salt.

    摘要: Aromatic hydrocarbons and particularly phenols and phenol ethers can be hydroxylated by reacting the aromatic compound with hydrogen peroxide in a reaction medium comprising trifluoromethanesulfonic acid. High yields of hydroxylated aromatic compounds are obtained by this process which avoids the use of extremely corrosive and difficult to handle agents. Phenol is hydroxylated predominantly to hydroquinone by this process.
