THE STANDARD THERMODYNAMIC FUNCTION OF TRANSFER OF RUBIDIUM TETRAPHENYLBORATE FROM WATER TO STRAIGHT-CHAIN N-ALKANOLS

Solubilities of RbBPh4 in water, methanol, ethanol, 1 - propanol, 1 - butanol, 1 pentanol, 1 - hexanol, 1 - hepanol and 1 - octanol at 288. 15 similar to 328. 15K have been determined by spectrophotometry. The standard transfer thermodynamic function of RbBPh4 from water to strai ght- chain alkanols at 288. 15 similar to 328. 15K has been calculated .
