Tetramethylammonium tetraphenylborate

Tetramethylammonium tetraphenylborate [15525-13-0] M 393.3. Recrystd from acetone, acetone/CCl4 and from acetone/1,2-dichloroethane. Dried over P2O5 in vacuum, or in a vacuum oven al 60° for several days. 

Figure 5. Effect of the supporting electrolyte cation in the nitrobenzene phase on the relationship between interfacial potential and dye iodide (DiOC2(3)1) concentration. A, 0.01 mol /L tetramethylammonium tetrapheny lb orate B, 0.01 mol/L tetraethylammonium tetrap heny lb orate C, 0.01 mol/L tetrabuty-lammonium tetrapheny lb orate D, two identical curves, 0.01 mol / L tetraphenylarsonium tetraphenylborate and 0.01 mol / L crystal violet tetraphenylborate. (The crystal violet has no supporting electrolyte in the nitrobenzene phase.) The supporting electrolyte in the water phase is always 0.01 mol/L LiCl, except for curve E, which has no supporting electrolytes.

Fig. 1.2.4 Cyclic voltammogram of the transfer of tetramethylammonium ions between water and nitrobenzene. c(TmeA ) = 4.7 x 10 mol L the supporting electrolyte is in the aqueous phase 0.1 mol L LiCl, and in nitrobenzene 0.1 mol L tetrabutylammonium tetraphenylborate the scan rate is 20 mV s .
