Crown ethers are macrocyclic ethers,which help to solvate metal cations,and thus allow inorganic salts to dissolve in organic solvents. 12-crown-4 15-crown-5 18-crown-6 18-crown-6 EPM of 18-crown-6 solvates LI solvates Nat solvates K' with K+solvated 18-Crown-6 is the ideal size to incorporate a potassium ion,and allows organic solutions of ionic potassium salts to be prepared (purple benzene).
