A discussion covers the different methods for the separation of the aldehyde products from the catalyst and any solvent during or after hydroformylation reactions of long chain alkenes (octene, hexene, pentene); aqueous, fluorous, and ionic liquid biphasic systems as well as systems involving scCO 2 sometimes in conjunction with one or other of the types of solvents; hybrid systems in which a liquid phase containing the catalyst is supported on a microporous solid support; the advantages and disadvantages of the various systems; new results concerning the addition of [1-octyl-3-methylimidazolium]Br to aqueous biphasic systems and the use of supercritical fluids to transport substrates over supported ionic liquid phases. This is an abstract of a paper presented at the DGMK/SCI-Conference "Synthesis Gas Chemistry" (Dresden, Germany 10/4-6/2006).
