Primary and secondary solvation binding constants and stoichiometries are reported for the protic solvation by pentadecafluorooctanol (PFO) and trifluoroethanol (TFE) of the non-bonding electrons on triethylamine (TEA) and on the oxygen of the proton-transfer complex formed by pentachlorophenol (PCP) and TEA. The solvation-sensitive apparent proton-transfer formation constant K P T is measured in varying low concentrations of the protic solvent S in benzene bulk solvent, and the solvation binding constants and stoichiometries are determined. A two-stage solvation model is supported, as observed in earlier studies of similar systems. The primary solvation stage involves a single solvent alcohol molecule, whereas the secondary stage involves several solvent molecules.
