Abstract: Acrylic acid practically devoid of water, acrolein, formaldehyde and acetic acid is obtained at particularly low cost by countercurrent scrubbing and quenching of the reaction gas formed in the catalytic oxidation of propylene and/or acrolein with a high-boiling, extremely hydrophobic solvent followed by processing of the extract.

Abstract: Process for manufacturing styrene, by catalytic dehydrogenation of ethylbenzene with oxygen or gases containing molecular oxygen in the presence of water vapor in a fluid bed at temperatures between 350 and 600º c, by the use of solid catalysts and regeneration of these catalysts by combustión, characterized by that the catalyst is regenerated by incompletely burning the carbonaceous deposits with oxygen or gases containing molecular oxygen only to such an extent that on average it contains during the transformation between 1 and 30% by weight, based on the catalyst, of said carbonaceous deposits.

Abstract: A process for the preparation of carbonyl compounds by oxidation of alcohols in the gas phase with a gas containing oxygen in the presence of catalysts containing copper or silver and a phosphorus compound that is volatile under the conditions of the reaction, the ratio of the mass of phosphorus to the mass of the alcohol being less than 0.5 ppm.

Abstract: A coated catalyst comprising (a) an inert carrier having particles of not less than 100 mu m diameter and a surface area of up to 20 m2/g and (b) a coating which contains the catalytic material and adheres firmly to the outer surface and to the edge zone, near the surface, of the carrier particles, can be prepared by applying the catalytic material as a 10-70% strength suspension in water to the agitated carrier particles, which are at below 70 DEG C., if the suspension is sprayed, at a constant rate of from 0.01 to 2.0 kg of active material/hour/liter of carrier onto the carrier particles, while at the same time uniformly passing from 0.1 to 12 m3 (S.T.P.)/hour/liter of carrier of an inert gas at from 20 DEG to 300 DEG C. over the carrier particles, under conditions such that the water only evaporates incompletely but the water content of the resulting coating is less than the maximum degree of saturation of the catalytic material.
