Apparent and partial molar volumes of quaternary phosphonium halides in aqueous solutions

Partial molar volumes and heat capacities of single ions in aqueous solution over the temperature range 288.15 to 328.15 KElectronic supplementary information (ESI) available: Densities, apparent molar volumes and apparent molar heat capacities of aqueous solutions of NaBPh4, Ph4PBr, Ph4PCl and NaBr. See http://www.rsc.org/suppdata/cp/b4/b407875f/

“…The partial molar volumes at infinite dilution for Ph 4 PCl in aqueous solution at various temperatures have been reported in previous studies, 29,[32][33][34] as indicated in Table 2 and Fig. 2a.…”

“…A comparison is given in Table 2 of the V 0 2 results determined in this work with data at the same temperatures taken from the literature. [28][29][30][31][32][33][34][35][36][37][38] In the published studies, analyses of the apparent molar volume data using eqn. (2), or an analogous equation expressed in terms of molar concentration, were carried out using values for A V that were based on the most reliable values for the relative permittivity of water that were available at the time.…”

Effect of Organic Cations and Solvents on the Ion-Pair Extraction of Boric Acid with Salicyl Alcohol

“…The difference between the ion-pair reagents, especially TOMACl and Ph 4 PBr, is ascribable to their hydrophobicity. TOMACl is highly hydrophobic but Ph 4 PBr is rather hydrophilic, as it dissolves in water [13,14]. To understand such extraction behavior of boric acid, it is necessary to elucidate the extraction equilibrium and the extractable species.…”

Hydration behaviour of some alkyl dithiocarbonates and their mixed-ligand oxalatochromate complexes

“…are the compressibilities of the solution and pure solvent respectively. The concentration dependence of K ~, ~~~ can be described by equation (6) where YK, is the experimental s10pe.~ The uncertainty in K, O is 1 x 104-1.5 x 1 0 4 cm3 mol-' bar-'.…”

“…Therefore it is convenient to express the concentration dependence 4a of K ~. ~~ in terms of equation (6).…”
