Tetrabutylammonium hexafluorophosphate Usage And Synthesis

Chemical Properties

Tetrabutylammonium hexafluorophosphate is a white powder, extremely soluble in polar organic solvents such as acetone and acetonitrile.

Uses

Tetrabutylammonium hexafluorophosphate can be used as a supporting electrolyte for the formation of cyclic disulfide moiety of 3,5-diimido-1,2-dithiolane derivatives by S-S coupling of dithioanilides.

Uses

Tetrabutylammonium hexafluorophosphate (TBAPF₆) or TBAHP can be used:

• As the supporting electrolyte in cyclic voltammetric studies.
• As a reactant in the synthesis of fluorescent nanofibrous sensing films for detecting nitro-explosive vapors.

Hazard

Tetrabutylammonium hexafluorophosphate is harmful to humans and is an eye and skin irritant. It may cause severe eye irritation. It may also cause respiratory irritation. Harmful if ingested.

Purification Methods

Recrystallise it from saturated EtOH/water and dry it for 10hours in a vacuum at 70o. Also recrystallise it three times from absolute EtOH and dry it for 2 days in a drying pistol under a vacuum at boiling toluene temperature [Bedard & Dahl J Am Chem Soc 108 5933 1986]. It is a stable supporting electrolyte in organic solvents [Baiser in Organic Electrochemitry M. Dekker NY p228 1973.]
