Use

Traces of water and acidic materials have been removed from it by refluxing with Na, K or CaH2, decanting and distilling from Na, K, CaH2 or LiAlH4. The reaction has been speeded up by using vigorous high-speed stirring with molten potassium. For virtually complete elimination of water, 1,2-dimethoxyethane has been dried with Na-K alloy until a characteristic blue colour is formed in the solvent at Dry-ice/cellosolve temperatures: the solvent is kept with the alloy until distilled for use [Ward J Am Chem Soc 83 1296 1961]. Alternatively, glyme, refluxed with benzophenone and Na-K, is dry enough if, on distillation, it gives a blue colour of the ketyl immediately on addition to benzophenone and sodium [Ayscough & Wilson J Chem Soc 5412 1963]. It has also been purified by distillation under N2 from sodium benzophenone ketyl (see above). [Beilstein 1 IV 2376.]
