The invention relates to a die () for the extrusion of catalyst molding, catalyst support molding, or adsorbent molding () in flow direction () of an extrudable composition from an entry side () to a discharge side () of the die comprising a shell () and comprising one or more channel-formers () which are displacers of the extrudable composition and which extend in flow direction of the extrudable composition, wherein the channel-formers () have been metal-printed. It is preferable that this is free from cavities for receiving extrudable composition which extend at right angles to the flow direction () of the extrudable composition, and that this is free from connections running at right angles from channel-formers () to the interior side wall () of the die (). The invention further relates to a process for the production, by means of 3D metal printing, of a metal-printed die () for the extrusion of catalyst moldings/support moldings ().

The present invention relates to a process for preparing 3-methyl-2-butenol (prenol) and 3-methyl-2-butenal (prenal) from 3-methyl-3-butenol (isoprenol), in which 3-methyl-3-butenol is subjected to a catalytic isomerization over a carbon-supported Pd catalyst in the presence of a gas mixture comprising 1% to 15% by volume of oxygen to obtain a first product mixture, and the first product mixture is subjected to an oxidative dehydrogenation over a Pd catalyst comprising SiOand/or AlOas support material, or over a carbon-supported Pd/Au catalyst in the presence of a gas mixture comprising 5% to 25% by volume of oxygen.

Process for producing prenol and prenal from isoprenol

Supported noble metal-comprising catalysts which can be obtained by a1) application of a noble metal compound, optionally in admixture with additives acting as promoters, to a support material, then drying, and a2) application of a reducing agent to a support material, then drying, wherein steps a1) and a2) are repeated simultaneously or in alternating turns, or wherein either of the compounds is applied entirely and then the other one is applied entirely, b) optionally afterwards drying of the resulting product, and c) subsequent calcination, its use, especially for oxidative dehydrogenation and a process for producing it.

Supported noble metal-comprising catalyst for oxidative dehydrogenation or epoxidation

A process for preparing shaped catalyst bodies whose active composition is a multielement oxide, in which a finely divided precursor mixture with addition of graphite having a specific particle size is shaped to the desired geometry and then treated thermally.

A process comprising: continuously distilling a crude xylylenediamine in a column to form a pure xylylenediamine and a bottom product, wherein the column comprises a distillation column having a side draw and the distillation column is operated under a reduced pressure and a bottom temperature of 185&#xb0; C. or less; drawing off the pure xylylenediamine from the side draw; evaporatively concentrating the bottom product of the distillation column in an additional evaporation stage to form a condensate; and returning the condensate into the distillation column.

Processes for preparing pure xylylenediamine

Processes for preparing a xylylenediamine by continuous hydrogenation, wherein the processes comprise: introducing a liquid circulation stream comprising a phthalonitrile and ammonia into a reactor to continuously hydrogenate the phthalonitrile in the presence of a heterogenous catalyst and the ammonia such that a reactor effluent comprising the xylylenediamine is formed; drawing off a portion of the reactor effluent to provide a first recycle stream; mixing at least a portion of the first recycle stream in a mixing unit with liquid ammonia and fresh phthalonitrile in solid or molten form to provide a second recycle stream; and recycling the second recycle stream to the liquid circulation stream, or wherein the second recycle stream and any remaining unmixed portion of the first recycle stream are both recycled to the liquid circulation stream.
