The enthalpies of dilution of Ph 4 PCl, Ph 4 AsCl, NaPh 4 B and R 4 NBr (where R is ethyl, n -propyl, n -butyl and n -pentyl) have been determined by flow microcalorimetry at 298.15 K in water. From the experimental data, the relative apparent molar enthalpies φ L were calculated with the aid of an extended Debye—Huckel equation. A comparison with literature values for some R 4 NBr was made. Ph 4 PCl and Ph 4 AsCl show similar behavior, unlike that of NaPh 4 B, which may be a consequence of the effect of the Na + ion in relation to the Cl − ion. |
