Tetrabutylammonium iodide Chemical Properties,Uses,Production

Chemical Properties

white or tan powder


Tetra-n-butylammonium Iodide is used in the preparation of novel quaternary amines to serve as antibacterial agents in the rise of drug-resistant bacteria. Also used in phosphonium reversible inhibito rs of cholinesterases.

Purification Methods

Crystallise the iodide from toluene/pet ether (see entry for the corresponding bromide), acetone, ethyl acetate, EtOH/diethyl ether, nitromethane, aqueous EtOH or water. Dry it at room temperature under a vacuum. It has also been dissolved in MeOH/acetone (1:3, 10mL/g), filtered and allowed to stand at room temperature to evaporate to ca half its original volume. Distilled water (1mL/g) is then added, and the precipitate is filtered off and dried. It can also be dissolved in acetone, precipitated by adding ether and dried in a vacuum at 90o for 2 days. It has also been recrystallised from CH2Cl2/pet ether or hexane, or anhydrous methanol and stored in a vacuum desiccator over H2SO4.
