The invention relates to a hydroformylation process in which at least one olefin having from 2 to 6 carbon atoms is reacted continuously with carbon monoxide and hydrogen in the presence of a hydroformylation catalyst in a reaction zone in which a liquid phase is present and a stream S) is taken from the liquid phase, heat is removed from this stream and the stream is subsequently returned to the reaction zone without removal of a material component.

Method for the hydroformylation of olefins with 2 to 6 carbon atoms

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.

Method for the hydroformylation of olefins comprising 2 to 8 carbon atoms

A process for preparing hydroformylation products of olefins having from 2 to 8 carbon atoms comprises The proposed coupling of the hydroformylation with, for example, a steam cracker allows complete hydroformylation of the olefins produced without olefin losses via the waste gas.
