18-Crown-6 Chemical Properties,Uses,Production

Chemical Properties

slightly yellow solid

Uses

A useful phase transfer catalyst.

Synthesis Reference(s)

The Journal of Organic Chemistry, 39, p. 2445, 1974 DOI: 10.1021/jo00930a037

Purification Methods

Recrystallise it from acetonitrile and dry it in a vacuum. Purify it also by precipitating the 18-crown-6/nitromethane 1:2 complex with Et2O/nitromethane (10:1 mixture). The complex is decomposed in vacuum whereby 18-crown-6 distils off under the reduced pressure. [Beilstein 19/12 V 601.]
