    Abstract: Selective hydrogenation of alpha , beta -ethylenically unsaturated aldehydes (II) to corresponding unsaturated alcohols (I) comprises performing reaction in a reactor containing a liquid phase, suspended catalyst and optionally a gas phase, The liquid phase and gas phase (if present) are supplied to the reactor through a device (A) with openings or channels having a hydraulic diameter of 0.5-2 mm. Selective hydrogenation of unsaturated aldehydes of formula R R C=CR -CHO (II) to corresponding alcohols of formula R R C=CR -CH2OH (I) comprises performing the reaction in a reactor containing a liquid phase, suspended catalyst and optionally a gas phase. The liquid phase and optionally the gas phase are supplied to the reactor through a device (A) with openings or channels having a hydraulic diameter of 0.5-2 mm. R , R = H, optionally substituted mono- or polyunsaturated 1-20C alkyl (sic; some of the groups exemplified in the disclosure are saturated), optionally substituted aryl or optionally substituted heterocyclyl; R = H or 1-4C alkyl.

    Abstract: The present invention relates to a method for producing n-butyraldehyde, 2-ethylhexyl alcohol and/or n-butanol from 1,3-butadiene-containing hydrocarbon streams, which comprises the following steps: a) reacting 1,3-butadiene with an amine of general formula (I) to form an amine of formula (II), whereby, in said formulae (I) and (II), the substituents R 1 and R 2 independently represent hydrogen or an appropriate organic radical from the group alkyl, alkenyl, cycloalkyl, alkoxyalkyl, aminoalkyl, monoalkylaminoalkyl, dialkylaminoalkyl, aryl and aralkyl, or R 1 and R 2 form a 3-to 7-membered heterocycle together with the nitrogen atom, which optionally comprises one or several double bonds and optionally one other heteroatom from the group N, O and S, in the presence of an amide of formula (III), in which R 3 and R 4 independently have the meaning indicated in the amines (I) and (II) for R 1 and R 2 and M represents an alkali metal; b) isomerizing the amine (II) to form an amine of formula (IV), in which R 1 and R 2 have the meaning indicated in the formulae (I) and (II) and c) releasing n-butyraldehyde as well as the amine of formula (I) by hydrolysis of said amine (IV) with water.

    Abstract: Nitrite is hydrogenated to primary amine using an activated macroporous Raney catalyst comprising alpha -alumina and transition metal(s), obtained by (i) shaping kneadable composition comprising an alloy, a shaping aid, water and a pore former, (ii) calcining and activating by treating with aqueous alkali metal hydroxide solution and (iii) rinsing with aqueous alkali metal hydroxide solution and water. Hydrogenating nitrite to primary amine involves using activated macroporous Raney catalyst comprising alpha -alumina and transition metal(s), such as iron, cobalt, nickel, titanium, zirconium, chromium and manganese. The Raney catalyst is obtained by preparing a kneadable composition comprising an alloy, a shaping aid, water and a pore former, which is then shaped to form a component. The shaped component is calcined and activated by treating with aqueous alkali metal hydroxide solution. The catalyst obtained is rinsed with aqueous alkali metal hydroxide solution and water. Independent claims are also included for the following: (1) a macroporous Raney catalyst; and (2) the production of a macroporous Raney catalyst.
