Properties and stability

Easily soluble in water, ethanol, chloroform and acetone, slightly soluble in benzene.

Storage method

This product should be sealed and stored in a dry and dark place.

Synthesis method

Neutralize 10% tetraethylammonium hydroxide aqueous solution with hydrochloric acid to obtain a tetraethylammonium chloride solution. The aqueous solution is evaporated to dryness, and the residue is recrystallized in an acetonitrile-acetone mixed solvent to obtain tetraethylammonium chloride. The product is vacuum dried in the presence of phosphorus pentoxide.
