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.
