Abstract: The present invention relates to a catalyst bed comprising silver catalyst bodies and a reactor comprising such a catalyst bed. Further, the invention relates to the use of the catalyst bed and the reactor for gas phase reactions, in particular for the oxidative dehydrogenation of organic compounds under exothermic conditions. In a preferred embodiment, the present invention relates to the preparation of olefinically unsaturated carbonyl compounds from olefinically unsaturated alcohols by oxidative dehydrogenation utilizing a catalyst bed comprising metallic silver catalyst bodies.

Abstract: In a process for preparing isoprenal and/or prenal by bringing a gaseous reactant stream comprising isoprenol into contact with a silver-containing heterogeneous catalyst in the presence of molecular oxygen to obtain an isoprenal and/or prenal-containing product stream, a weight ratio of formaldehyde to isoprenol of less than 0.04 is maintained in the reactant stream. The process maintains high conversion and selectivity over time and avoids catalyst clogging and pressure drop.

Abstract: The presently claimed invention relates to a process for the recovery of 3-methyl-3-buten- -ol from a stream comprising (Z)-3-methylpent-2-ene-1,5-diol, (E)-3-methylpent-2-ene-,5-diol and 3-methylenepentane-1,5-diol by treating the stream with isobutene and water.
