Tetrabutylammonium hexafluorophosphate Usage And Synthesis

Chemical Properties

off-white powder

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.

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.]
