Abstract
The integral heats of solution, ΔHs, of Bu4NBr in water, determined from 45 to 75°C, have been combined with integral heats of solution from 3 to 35°C reported earlier to derive excess partial molal heat capacities, text-decoration:overlineC°pE, of Bu4NBr in water from 4 to 70°C. text-decoration:overlineC°pE decreases from 4 to 25° but remains unchanged from 25° to 70°C. The temperature dependence of text-decoration:overlineC°pE for Bu4NBr in water is discussed in terms of the structural changes occurring in solution. Comparison of the temperature dependence of text-decoration:overlineC°pE for aqueous solutions of Bu4NBr with that for aqueous solutions of NaBPh4 shows that non-polar groups of aliphatic hydrocarbons affect water structure differently from those of aromatic hydrocarbons. An attempt has been made of explain this difference.
