Abstract
The abilities of various cyclic and acyclic polyethers to solubilize potassium permanganate in organic solvents have been compared. In general, the cyclic compounds (crown ethers) are more effective than acyclic polyethers of comparable molecular weights. Each mole of 18-crown-6 is capable of solubilizing one mole of potassium permanganate in most solvents whereas the corresponding linear polymer, dimethyloctaethylene glycol, is much less effective, particularly in solvents of low polarity. Very long chain polymers are capable of complexing more than one mole of potassium ion per mole of polyether and thus bringing more than one mole of potassium permanganate into solution. A comparison with other studies on acyclic polyethylene glycols suggests that these structures would be helical with the oxygen complexed potassium ions inside and the permanganate anions arranged along the exterior.
