Solubilities (c) of sodium tetraphenylborate in methanol, ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-octanol at 288.15, 298.15, 308.15, 328.15 K were determine by the spectrophotometry. The data can be expressed by lg c = 0.9090 + (-0.4545 + 0.1520 lg T) (10 + n), where n is the no. of carbon atoms in the straight-chain monohydric alcs. The standard free energies of transfer (DG0) of sodium tetraphenylborate from water to the straight chains monohydric alcs. at 298.15 K were calculated The results can be expressed as DG0 = 55.75 exp(-0.0881 D), where D is the dielec. constant of the alcohol When DGt0 is plotted against n, a straight line is obtained. The results can be expressed as DGt0 = -4.92 ?10-3 + 3.08 n.
