    摘要: Olefins having from 2 to 8 carbon atoms are hydroformylated in a process in which (i) an olefin-containing feed in which a proportion of a saturated hydrocarbon having from 2 to 8 carbon atoms is present and also carbon monoxide and hydrogen are fed into a reaction zone and reacted in the presence of a hydroformylation catalyst, (ii) a stream consisting essentially of unreacted olefin and saturated hydrocarbon is separated off from the output from the reaction zone, (iii) the stream is separated into an olefin-enriched fraction and an olefin-depleted fraction by rectification, and (iv) at least part of the olefin-enriched fraction is recirculated to the reaction zone.

    摘要: In a process for the fractional distillation of a liquid crude aldehyde mixture including straight-chain and branched aldehydes, the product mixture is fractionated in a first distillation column to give a product stream of branched aldehyde, a product stream of straight-chain aldehyde and a further product stream including straight-chain aldehyde and the high boiling constituents. The further product stream is then fractionated in a second distillation column whose packing volume is a factor of from 50 to 200 smaller than that of the first distillation column to give a product stream of straight-chain aldehyde and a high boiler product stream.

    摘要: In a process for the hydroformylation of olefins having from 12 to 100 carbon atoms in the presence of a cobalt carbonyl catalyst at pressures of from 100 to 400 bar and at from 100 to 200° C., depressurization and recovery of the cobalt catalyst by extraction with an aqueous acid solution in the presence of atmospheric oxygen, (a) the extraction is carried out in the presence of a polymeric emulsion breaker selected from the group consisting of alkoxylated compounds containing amino, imino or OH groups, and (b) to achieve complete phase separation in the organic phase still containing small amounts of aqueous phase, the formation of relatively large droplets of the dispersed aqueous phase is effected in a coalescence stage.
