Abstract
E and Z isomers of alkene alcohols 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.
