Thermoregulated Microemulsions by Cyclodextrin Sequestration: A New Approach to Efficient Catalyst Recovery

The combination of imidazolium surfactants with α‐cyclodextrins (CDs, in green) was used as a control element in the thermoregulated aqueous olefin hydroformylation. The self‐assembly of the imidazolium surfactants (red) favors the micellization process at high temperatures, whereas at lower tempera...

Summary:The combination of imidazolium surfactants with α‐cyclodextrins (CDs, in green) was used as a control element in the thermoregulated aqueous olefin hydroformylation. The self‐assembly of the imidazolium surfactants (red) favors the micellization process at high temperatures, whereas at lower temperatures the complexation of the surfactant monomers into the α‐CDs is favored.
