摘要： A process is provided for the recovery of an optionally substituted C.sub.7 to C.sub.17 aldehyde from a liquid hydroformylation product medium obtained by rhodium catalyzed hydroformylation of an optionally substituted C.sub.6 to C.sub.16 olefin which contains (i) a rhodium complex hydroformylation catalyst containing rhodium in complex combination with carbon monoxide and with a ligand, (ii) excess ligand, (iii) at least one optionally substituted C.sub.7 to C.sub.17 aldehyde, and (iv) aldehyde condensation products, which process comprises:(a) degassing said liquid hydroformylation medium;(b) passing the degassed liquid hydroformylation medium through an evaporation zone maintained under temperature and pressure conditions conducive to evaporation of said at least one C.sub.7 to C.sub.17 aldehyde;(c) recovering from the evaporation zone a liquid catalyst-containing stream;(d) cooling the catalyst-containing stream exiting the evaporation zone;(e) recovering a vaporous stream from the evaporation zone containing (i) at least one optionally substituted C.sub.7 to C.sub.17 aldehyde, (ii) ligand and (iii) a minor amount of said aldehyde condensation products;(f) passing said vaporous stream to a fractionation zone;(g) recovering from said fractionation zone (i) a vaporous product stream containing said at least one C.sub.7 to C.sub.17 aldehyde, and (ii) a liquid bottom stream containing said ligand and aldehyde condensation products; and(h) recycling said cooled catalyst-containing stream of step (d) and at least a part of the material of said liquid bottom stream of step (g) to said hydroformylation zone.

摘要： Hydrogen is supplied first to a last hydrogenation zone, and gases recovered from the last hydrogenation zone are passed to the first hydrogenation zone of a continuous multi-zone liquid phase process for hydrogenating an organic compound to a corresponding hydrogenation product. The organic compound, with a suitable diluent or recycle hydrogenation product, flows successively through the zones beginning with the first and ending with the last hydrogenation zone to undergo hydrogenation with the hydrogenation product being recovered from the last hydrogenation zone.
