Beschreibung
Zusammenfassung:	A method for separating a water soluble noble metal catalyst from a crude reaction product of a noble metal-catalyzed process for preparing octadienol from butadiene in aqueous solution, in an aqueous emulsion or as an aqueous suspension, the crude reaction product including an aqueous phase containing a water soluble Group VIII noble metal-ligand complex catalyst, and an organic phase containing unreacted butadiene feed and an organic octadienol reaction product, which comprises: (a) contacting the crude reaction product with a hydrophobic membrane capable of allowing a substantial portion of the unreacted butadiene feed and organic octadienol reaction product to pass therethrough while retaining a substantial portion of the water soluble Group VIII noble metal-ligand complex catalyst; (b) removing unreacted butadiene feed and the organic octadienol reaction product which passes through the hydrophobic membrane as permeate; and (c) retaining the water soluble Group VIII noble metal-ligand complex catalyst as retentate.
