    Abstract: A solid bed catalyst containing either palladium and selenium and/or tellurium on a silica carrier, has a BET surface area of 80-380 m /g, a pore volume of 0.6-0.95 cm /g and a pore diameter of 3 nm to 300 mu m. The proportion of the pore volume with a pore diameter of 10-100 nm is 80-95%. Also claimed are: (i) the preparation of the above catalyst; and (ii) the preparation of 2-buten-1-ol compounds of formula H2R1C-R2C=CR3-CR4R5-OR6 (I) by isomerising 3-buten-1-ol compounds of formula HR1C=CR2-CHR3-CR4R5-OR6 (II) in the presence of hydrogen and the catalyst. In the formulae: R1-R6 = H or aliphatic group (optionally substituted with OH, OR, halogen or carboxyl), or R2 may also be -CHO, or R2 and R5 can combine with the C atoms between them to form an alicyclic ring, or R6 can also be a cycloaliphatic, arylaliphatic or aromatic group or a group of formula C(=O)-R7; R = aliphatic group; and R7 = aliphatic, cycloaliphatic, arylaliphatic or aromatic group.

    Abstract: In the production of aliphatic alpha ,w-aminonitriles (I) by catalytic partial hydrogenation of aliphatic alpha ,w-dinitriles (II), the catalyst contains: (a) iron (Fe) and/or Fe compound(s); (b) 0.01-5 wt.%, with respect to (a), of a promoter based on group 2, 3, 4 or 5 elements selected from aluminium, silicon, zirconium, titanium and vanadium; and (c) 0-0.5 wt.%, with respect to (a), of an alkali(ne earth) metal compound. Preferably component (a) is based on Fe oxide(s) and (b) on Al, Si and V. The catalyst is optionally supported. Simultaneous production of ACN and HMD from ADN comprises: (1) catalytic partial hydrogenation of ADN to a mixture containing ACN, HMD and ADN; (2) separation of ACN and HMD from the mixture; (3) adding an acid or acid ion exchanger to the mixture containing ADN especially in an amount of 0.01-10 wt.% with respect to ADN, ADN is then separated. If ADN is separated by distillation, the acid used has a boiling point above that of ADN at the pressure used for distillation and a pKa value \} 10. The purified ADN is then recycled. Hydrogenation may be carried out in a suspension or stationary bed reactor.
