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.

Purpose

Phase transfer catalysts for polymerization reactions. Membranes carry electrolytes for research. Test for antimony and bismuth, and determine gold. Polarographic analysis.
