18-Crown-6 is the simplest crown ether that can be prepared by reacting triethylene glycol with triethylene glycol dichloride in the presence of potassium hydroxide as a base. 18-Crown-6 can solubilize metal salts, particularly potassium salts, in nonpolar and dipolar aprotic solvents. Thus, it is widely used as a phase transfer catalyst.
