Abstract: In the production of 6-30C aldehydes and/or alcohols (A) by hydroformylation, the reaction mixture (olefins, synthesis gas and catalysts, or their precursors) is introduced into the reactor through a nozzle with adjustable transmission cross-section. Reaction is at 120-210 deg C and 100-400 bar and the reaction mixture is introduced at high speed into a high-pressure reactor. An Independent claim is also included for a reactor for production of (A) by the new process.

Abstract: The continuous hydroformylation of 6-20C olefins with hydrogen and carbon monoxide, with regeneration and recycling of the cobalt catalyst, is carried out with aqueous cobalt(II) salt solution. A continuous process for the hydroformylation of 6-20C olefins (I) by: (a) contacting an aqueous cobalt(II) salt solution with hydrogen and carbon monoxide to form a hydroformylation catalyst and then bringing the aqueous catalyst phase into intimate contact with (I), optional organic solvent and H2 plus CO so that the catalyst is extracted into the organic phase and (I) is hydroformylated; (b) treating the product from the reaction zone with oxygen in presence of acid aqueous Co salt solution so that the catalyst is decomposed to form Co(II) salts which are back-extracted into the aqueous phase, and then separating the phases; and (c) returning the aqueous Co(II) salt solution unchanged to stage (a). The Co(II) salt solution has a concentration of 1.1-1.7 wt% (as cobalt) and is always kept under conditions such that the solubility limit of Co(II) formate in water is not exceeded.

Abstract: Procedimiento continuo para el hidroformilado de olefinas con 6 a 20 átomos de carbono, en el que a) se pone en contacto íntimo una disolución acuosa de sal de cobalto (II) con hidrógeno y monóxido de carbono, bajo formación de un catalizador de cobalto activo en hidroformilado, se pone en contacto íntimo la fase acuosa que contiene catalizador de cobalto, en al menos una zona de reacción, con las olefinas, y en caso dado un disolvente orgánico, así como hidrógeno y monóxido de carbono, extrayéndose el catalizador de cobalto en la fase orgánica, e hidroformilándose las olefinas, b) se trata la descarga de la zona de reacción con oxígeno en presencia de disolución acuosa ácida de sal de cobalto (II), descomponiéndose el catalizador de cobalto bajo formación de sales de cobalto (II), y extrayéndose de nuevo estas en la fase acuosa; y se separan a continuación las fases, c) se conduce la disolución acuosa de sal de cobalto (II) sin modificar de nuevo al paso a), presentando la disolución de sal de cobalto (II) una concentración de un 1, 1 a un 1, 7 % en peso, referido a cobalto, y manteniéndose permanentemente la misma bajo condiciones en las que no se sobrepasa el límite de solubilidad de formiato de cobalto (II) en agua, manteniéndose el valor de pH de la disolución de sal de cobalto (II) en el intervalo de 2 a 4, y manteniéndose todas las partes de instalación fuera de la zona de reacción, que están en contacto con la disolución acuosa de sal de cobalto (II) según determinación, a una temperatura de al menos 40ºC.

Abstract: Olefins having from 6 to 20 carbon atoms are hydroformylated by means of a continuous process in whicha) an aqueous cobalt(II) salt solution is brought into intimate contact with hydrogen and carbon monoxide to form a hydroformylation-active cobalt catalyst, and the aqueous phase comprising the cobalt catalyst is brought into intimate contact with the olefins and, if desired, an organic solvent and also hydrogen and carbon monoxide in at least one reaction zone where the cobalt catalyst is extracted into the organic phase and the olefins are hydroformylated,b) the output from the reaction zone is treated with oxygen in the presence of acidic aqueous cobalt(II) salt solution, with the cobalt catalyst being decomposed to form cobalt(II) salts and these being backextracted into the aqueous phase; and the phases are subsequently separated,c) the aqueous cobalt(II) salt solution is recirculated in unchanged form to step a), wherein the cobalt(II) salt solution has a concentration of from 1.1 to 1.7% by weight, calculated as cobalt, and is continually maintained under conditions under which the solubility limit of cobalt(II) formate in water is not exceeded.The process allows stable, trouble-free long-term operation.
