Abstract: A supported catalyst, containing vanadium pentoxide, titanium dioxide, phosphorus, rubidium and any optionally added cesium, with or without zirconium dioxide, in which the catalytic material contains from 1 to 40% by weight of V2O5, from 60 to 99% by weight of TiO2 and/or ZrO2 and, based on the total amount of TiO2, ZrO2 and V2O5, up to 2% by weight of phosphorus and up to 1.5% by weight of rubidium and/or cesium, and which comprises two layers, of which the inner layer contains more than 0.2 and up to 2% by weight of phosphorus, but no rubidium and/or cesium, and the outer layer contains from 0 to 0.2% by weight of phosphorus and from 0.02 to 1.5% by weight of rubidium and/or cesium, the outer layer accounting for from 10 to 90% by weight of the total catalytic material.

Abstract: A process for the separation of rhodium from a solution containing a rhodium carbonyl complex such as is obtained in the carbonylation of an alkanol or of an olefinically or acetylenically unsaturated compound with carbon monoxide and water and conversion of the separated rhodium into a soluble rhodium carbonyl complex, in which the solution containing the rhodium carbonyl complex is treated with hydrogen in the presence of a carrier substance at a temperature of from 25 DEG to 300 DEG C and at a pressure of from 1 to 700 atmospheres, the solution freed from rhodium is separated and the rhodium precipitated on the carrier is converted into a soluble rhodium carbonyl complex by treatment with carbon monoxide in the presence of a solvent and a compound which can replace the carbon monoxide as a ligand at a temperature of from 20 DEG to 300 DEG C and at a pressure of from 1 to 700 atmospheres.

Abstract: In a process for returning liquid in a gas stream by passing the liquid into a tube with gas flowing along the wall, (i) the liquid is passed through a ring fitted in the tube in the direction of the middle axis of the tube; and (ii) the liquid on the inside of the ring is peeled off and carried along by the gas stream.

Abstract: Process for the preparation of N,N-dialkylarylamines (I) by reacting arylamines (II) with alcohols (IIIa) or dialkyl ethers (IIIb) in the presence of an oxyacid of phosphorus or of an ammonium salt thereof as catalyst, characterised in that the oxyacid of phosphorus is reacted with an arylamine (IV) before the beginning of the reaction. The invention furthermore relates to the regeneration of the catalyst, by interrupting the reaction occasionally and treating the catalyst phase with steam or water at 100 to 300 DEG C.

Abstract: A process for reactivating a vanadium-containing oxidation catalyst, wherein the catalyst is treated first at from 100 DEG to 600 DEG C., with a volatile phosphorus compound in the presence of an oxygen-containing gas, and then at from 50 DEG to 600 DEG C. with sulfur trioxide or a mixture of a volatile sulfur compound and an oxygen-containing gas.
