Abstract: The invention concerns a process for preparing phthalides of general formula (I), in which R , R , R and R , independently of each other, designate hydrogen, C1-C4 alkyl or C1-C4 alkoxy, by the hydrogenation of phthalic acid anhydrides of general formula (II), in which the groups R , R , R and R have the above meanings, by means of hydrogenating catalysts. Hydrogenation is carried out by means of nickel catalysts doped with metals of the first, sixth and/or seventh subgroup of the periodic system.

Abstract: Heterocyclic aldehydes having the formula (I), in which A, B stand for possibly substituted methylene groups; m, n = 1 to 5 and m+n > 2, are prepared by hydrogenating carboxylic acids having the formula (IIa) or their esters (IIb) derived from C1-C10 alcohols at 200 to 450 DEG C in the presence of a catalyst. The products thus obtained are useful as precursors of cyclohexenone type herbicides.

Abstract: Process for producing aldehydes of formula (I) by hydrogenation of esters of formula (II), comprises gas-phase reaction of the ester with a 2-200 molar excess of hydrogen at 200-450 deg C in the presence of a heterogeneous catalyst, with recycle of unreacted hydrogen and ester. By-produced alcohol R'OH is removed from the recycle stream at least to the extent that the molar ratio of alcohol to ester in the reaction mixture is no more than 1:1. RCHO (I) RCOOR' (II) R = an aliphatic, cycloaliphatic, aromatic or araliphatic group that is optionally substituted and/or contains heteroatoms, and R' = residue of a 1-10C alcohol

Abstract: This invention concerns a catalyst, particularly for selective production of aromatics from a hydrocarbon stream with straight-chained, branched or cyclic alkyl or alkylene chains, of 6 to 12 carbon atoms. On an oxide of a transition metal of group IVB of the periodic table, such as TiO2 or ZrO2, this catalyst contains at least one element from the VIIIth secondary group, such as palladium, platinum, rhodium, rhenium or tin, and, optionally, a compound of alkali or earth alkali metals, a compound from the third major or secondary group, or zinc, or at least one compound from the sulphur, tellurium, arsenic, antimony or selenium group. The invention also concerns the use of this catalyst for producing aromatics, such as ethyl benzene or xylolene from C6 to C12-hydrocarbons.
