“…More recently, Ishak et al investigated the temperature dependence of dibutyl phthalate (DBP) and its isomer diisobutyl phthalate (DIBP) [24]. They show that DBP is more hydrophobic than its counterpart through a combination of measurements of relative water solubility and determination of octanol-water partition coefficients.…”

“…Similar results are also seen for dinonyl phthalate where the solubility of diesters with branched chains are higher than linear chains as reported by Letinski et al [20] In the same paper it was noted that DEHP also has a higher solubility than DnOP, however in both cases data is only available at 22°C. Aqueous solubility for DBP and DIBP obtained by Ishak et al [24] and calculations are compared in Table 2. The calculation of the solubility by Cousins and Mackay is simply a linear relation with the molecular volume and so does not differ significantly between isomers but is otherwise a close approximation.…”

“…A substantial but older list of vapour pressures and their correlation with ΔH vap was provided by Thomsen and Carlsen [29]. For some materials there is more precise new data such as that of Ishak et al [24] and by Gobble and Chickos [30]. As seen by the data plotted in Figs.…”

Plasticisers are widely used to provide desirable mechanical properties of many polymeric materials. These small molecule additives are also known to leach from the finished products, and this not only may modify the physical properties but the distribution of these materials in the environment and in the human body can cause long-term health concerns and environmental challenges. Many of these plasticisers are esters of polyvalent acids and phthalic acid has previously been predominant but various alternatives are now being more widely explored. The eventual distribution of these compounds depends not just on solubility in aqueous media and on vapour pressure but also on their interaction with other materials, particularly lipids and amphiphiles. This review provides an overview of both the basic physical data (solubility, partition coefficients, surface tension, vapour pressure) that is available in the literature and summarises what has been learnt about the molecular interactions of various plasticisers with surfactants and lipids.

“…Turbidimetry and nephelometry are also used but they are based on the precipitation of material and, due to the possibility of over-saturation, might be inaccurate [8]. The "saturation shake-flask method" is also widespread but it is time consuming [9][10][11][12][13][14][15][16][17]. The "generator column" method highly facilitates the reaching of solubility equilibrium [18] as the contacting area between the solid material and solvent is very high and the saturation concentration can be measured as usual in chromatography.…”

In this report, the solubility of hydroquinone (1,4-dihydroxybenzene) was determined in dichloromethane, trichloromethane and carbon tetrachloride at 298 K by using cyclic voltammetry. By the proposed cosolvent calibration method a mixed solvent was used for the determination of solubility where acetonitrile was the co-solvent. The molar ratios of the two solvents were uniform during the whole procedure both in the calibration solutions and in solutions used for solubility determinations. The solubility of hydroquinone decreased by the decrease of solvent permittivity, which were in dichloromethane 5.683 mmol•L −1 , in trichloromethane 2.785 mmol•L −1 and in carbon tetrachloride 0.321 mmol•L −1 .

The removal and detection of toxic analytes, including monomers and plasticizers, is important for both health and the environment. Potential absorbents and/or sensing materials are successfully made from polyaniline (PANI) and PANI doped with 10 wt.% of aluminum oxide (PANI‐Al2O3) and titanium dioxide (PANI‐TiO2). The amount of metal oxide incorporated into the surface layers of the polymer and the total amount incorporated are confirmed by energy dispersive X‐rays (EDX) and microwave plasma‐ atomic emission spectroscopy (MP‐AES), respectively. All three materials are evaluated as potential sensing materials and/or absorbents for styrene, monobutyl phthalate (MBP), and dibutyl phthalate (DBP) at 100 ppm in aqueous solutions. It is found that incorporating TiO2 into PANI improved both the sensitivity and selectivity to styrene, making PANI‐TiO2 a good absorbent and potential sensing material for styrene. Additionally, incorporating Al2O3 into PANI improved the sorption to MBP, but reduced the selectivity. As a proof‐of‐concept, the responses of the polymeric nanocomposites are combined and analyzed using principal component analysis (PCA) as such an algorithm. The output reveals good separation of the responses to each analyte, thereby demonstrating how sensing materials with poorer selectivity can be used together to overcome limitations in selectivity.
