Description

Application

Can be useful as phase-transfer catalysts.

Achiral crown ether (18-Crown-6) may be used as the mobile phase in capillary electrochromatography, used for enantiomeric separation of 15 cationic compounds.

Other Notes

Macrocyclic polyethers with repeating (-CH2CH2O) units. The compounds are ionophoric (form stable complexes with cations).

General description

18-Crown-6 is a crown ether. Crown ethers are large ring polyethers. These compounds are cyclic polymers of ethylene glycol, named in the form x-crown-y, where x denotes the total number of atoms in the ring and y is number of oxygens. Hence, 18-Crown-6 is basically the cyclic hexamer of ethylene glycol.
