STANDARD GIBBS ENERGIES OF TRANSFER OF RUBIDIUM TETRAPHENYLBORATE FROM WATER TO STRAIGHT-CHAIN N-ALKANOLS

Solubilities of ribidium tetraphenylborate in water, methanol, ethanol , 1-propanol, 1-butanol, 1-pentanol, 1-hexanol and 1-octanol at 288.15 , 298.15, 308.15, 318.15, 328.15 K have been determined by spectrophot ometry. The standard Gibbs energy of transfer of ribidium tetraphenylb orate from water to straight-chain n-alkanols and the primary medium e ffect of rubidium tetraphenylborate from 288.15 to 328.15 K have been calculated. Furthermore, the contribution of microscopic interactions to the standard Gibbs energy of transfer of rubidium tetraphenylborate is calculated and discussed.
