“…The purity of the final samples was checked by measuring their densities at 298.15 t 0.01 K , which agreed to within 20.00005 g cm-' with the literature values (9)(10)(11)(12). Since the surface properties of these reagents were involved in the present work, we also determined their surface tension at 293.15 5 0.01 K before and after adsorption (for 72 h at 308.15 5 0.2 K) on silica gel (0.3 g in 10 mL of the pure liquid) by a modified double capillary rise method (13).…”

The adsorption behaviour of benzene (A), toluene (A), p-xylene (A), and o-xylene (A) in their binary mixtures with o-chlorotoluene (B) on silica gel has been studied at 308.15 K. The data have been analysed in terms of a model that assumes that partition and surface reactions play an important role in the adsorption process, and have revealed that while both partition and surface reactions dictate the adsorption (U-shaped isotherms) of o-chlorotoluene (OCTE) (B) from benzene (A) or toluene (A) + OCTE (B) mixtures, the adsorption of A and B entities of p-xylene (A) or o-xylene (A) + OCTE (B) mixtures (S-shaped isotherms) onto the silica gel surface is governed primarily by the distribution process and secondarily by the surface reaction.

The solubility parameter is frequently used to screen potential solvents for a variety of applications. Solubility parameters for pure components are well documented; however, solvents used in industrial settings are usually mixtures. In this work, the mixture solubility parameter is defined in terms of experimentally measured properties. Mixture solubility parameters calculated from experiments are compared to two different methodologies: calculations using an ideal mixture assumption and calculations using the Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) equation of state. It is shown that for a wide range of mixtures, the ideal mixture assumption and PC-SAFT calculations both give good agreement with experimental mixture solubility parameters. The agreement of the ideal mixture calculations with experiment does not signify these mixtures are ideal. This occurs becausefor these particular systems. Chloroform/ketone systems present a case for which the ideal mixture assumption cannot predict the experimental mixture solubility parameters, while PC-SAFT calculations yield good agreement. Finally, the natural ability of the PC-SAFT approach to calculate Hansen partial solubility parameters due to the appropriate partitioning of energetic degrees of freedom is briefly discussed.
