The Uses of Dicyclohexano-18-crown-6
Anion activator, and complexing agent which solubilizes alkali metal ions in non-polar solvents.
Safety Profile
Poison by ingestion, skin contact, and intraperitoneal routes. An experimental teratogen. An eye and skin irritant. When heated to decomposition it emits acrid smoke and fumes.
Purification Methods
Purify it by chromatography on neutral alumina and eluting with an ether/hexane mixture [see Izatt et al. Inorg Chem 14 3132 1975]. Dissolve it in ether at ca 40o, and spectroscopic grade MeCN is added to the solution, which is then chilled. The crown ether precipitates and is filtered off. It is dried in vacuo at room temperature [Wallace J Phys Chem 89 1357 1985]. [V.gtle ed. Top Corr Chem (Host Guest Complex Chemistry) 98 1981.] SKIN IRRITANT.
