E and Z isomers of alkene alcohol and/or alkene alcohol derivatives are separated by substantially continuously contacting an ion exchange medium which is ion exchanged with silver and/or copper ions with the feed stream comprising the E and Z isomers of at least one alkene alcohol and/or at least one alkene alcohol derivative, then removing a product stream having a higher concentration of the E or Z isomer of at least one alkene alcohol or derivative of the alkene alcohol relative to the concentration of the E or Z isomer of the alkene alcohol or derivative of the alkene alcohol in the feed stream.
Les isomères E et Z d~un alcool d~alcène et/ou de dérivés d~un alcool d~alcène sont séparés en mettant en contact sensiblement de façon continuelle un milieu d~échange d~ions qui est échangé en ions avec des ions argent et/ou des ions cuivre avec le courant d~alimentation comprenant les isomères E et Z d~au moins un alcool d~alcène et/ou au moins un dérivé d~alcool d~alcène, puis en retirant un courant de produit ayant une concentration plus élevée de l~isomère E ou Z d~au moins un alcool d~alcène ou d~un dérivé de l~alcool d~alcène par rapport à la concentration de l~isomère E ou Z de l~alcool d~alcène ou du dérivé de l~alcool d~alcène dans le courant d~alimentation.
