Abstract: A process is disclosed for the selective hydrogenation of butine-2-diol(1,4) to butene-2-diol(1,4) using a palladium catalyst to which copper and zinc or silver and zinc are added as doping agents. In the preferred embodiment, it has been possible, by optimizing the composition of the catalyst, to improve the activity and selectivity of the catalysts in question while also eliminating the need to handle toxic substances during the catalyst manufacturing process.

Abstract: Prepn. is claimed of aldehydes by gas-phase hydrogenation of aromatic carboxylic acids, or aliphatic carboxylic acids which possessup to one hydrogen atom alpha to the carboxyl or esters or anhydrides of these acids, at temps. of 300 to 450 deg.C and pressures of 0.1 10 bar aided by special iron as catalysts. Cpds are prepd. by burning carbonyls in air and oxygen to the required level of iron oxide, and may be impregnated into an inert carrier of suitable particle size and mixed with an appropriate lubricant for use in a fluidised bed reactor.

Abstract: Isomerisation of alpha-ionone or beta-ionone to the thermodynamic equilibrium between the 2 cpds. is at 60-300 (150-250) deg.C, (a) in homogeneous phase in presence of salts of a Gp. VIIIb metal, in alkanols or N-methylpyrrolidone, or (b) in heterogeneous phase in presence of alpha-Al2O3, gamma-Al2O3 or alkali halides. (a) Isomerisation is at 60-150 deg.C, in presence of salts of Rh, Ru or Ni, esp. in presence of RhCl3 hydrate, RuCl3 hydrated or (PPh3)3RuCl2 in a 1-5C alkanol, or of Ni acetonylacetonate in N-methylpyrrolidone. (b) Reaction is in presence of alpha-Al2O3 at 200-250 deg.C or of alpha- or gamma-Al2O3 contg. PdO, or at 100-200 deg.C in presence of a catalyst contg. KF on gamma-Al2O3. USE - Beta-ionone is a raw material for synthesis of vitamin A. Alpha-ionone and/or beta-ionone is a perfume and aroma.
