“…Tetrachlorocatechol, with a p K a value of 5.83, has a total solubility of 70.5 g/m 3 [33] and an undissociated species concentration of 58.8 g/m 3 at pH 5.13 [33]. Although no correction was necessary for the effect of dissociation on the solubilities of some of these compounds [33–35], corrections were made in the current study where p K a and pH values are available. Similarly, for the mono‐, di‐, and trichlorophenols, the effect of dissociation is relatively insignificant but was nonetheless taken into account.…”

Abstract-A group contribution method is developed to estimate the supercooled liquid vapor pressure and the activity coefficients in water and octanol at 25ЊC of 98 selected monoaromatic compounds, many of which are or have been produced as chlorinated by-products in the manufacture of pulp and paper. The set includes alkylphenols, chlorinated phenols, anisoles, catechols, cymenes, guaiacols, syringols, and veratroles. The method can be used to estimate vapor pressures, solubilities in water, octanol-water partition coefficients, octanol-air partition coefficients, and Henry's law constants. It can also be used for predicting these partition coefficients as well as solubilities and vapor pressures for these and structurally similar compounds.

“…In fact, in presence of [C 4 C 4 Im][NTf 2 ] the extraction rate was faster than with [C 6 C 6 Im][NTf 2 ]. This behavior can also be related to the polarity of the proton in the cation [45] From these results and in presence of concentrated solutions (1 wt.% C), the [C 1 C 6 Im][NTf 2 ] IL led to the maximal extraction of guaiacol from water (see SI Fig. S14).…”

“…In fact, increasing the temperature lowered the amount of extracted guaiacol. This result was related to the solubility of guaiacol in water which increased together with temperature, inducing a decrease of the partition coefficient between guaiacol and the ILs [45]. For all ILs, with ultrasonic stirring, the reaction was slower compared to the reaction performed under mechanical stirring at the same temperature.…”

Characterizing the Effects of a “Switchable Water” Additive on the Aqueous Solubility of Small Molecules

"Switchable water" is an aqueous solution containing a water-soluble amine additive that exhibits CO -switchable properties, such as large changes in ionic strength, by forming an ammonium bicarbonate salt. Switchable water has been used to reversibly "salt-out" organic compounds from water. This study explores the salting out of several compounds in switchable water when CO is present and also explores the solubility of small molecules in switchable water, compared to pure water, when CO is absent. The results show that organic compounds are generally more soluble in switchable water than pure water in the absence of CO , but less soluble in the presence of 1 atm CO . Exceptions include carboxylic acids and phenols which, presumably due to their acidity, are more soluble in switchable water than in pure water, even when CO is applied. Kirkwood-Buff solvation theory was applied to gain insights into the effects of the amine additive on the aqueous solubility of caffeine. Furthermore, the switchable properties of the additives allow for the preparation of switchable aqueous two-phase systems.
