摘要：

Enthalpies of solution of Ph4PI and NaBPh4 in rnethanol-N,N-dimethylformamide (DMF) mixtures have been measured within the whole range of the mixed solvent composition. The ionic contribution to the transfer enthalpy from methanol to methanol-DMF mixtures based on the assumption that ΔHtXXX(BPh-4) = ΔHtxxx(Ph4P+), has been calculated using the data obtained and earlier data for NaI solution. The single-ion transfer enthalpies change monotonically with the mixture's composition, without any extrema typical of the systems containing water as a component of the mixed solvent. © 1990.
