“…Shown in panel a of Fig. 6 are simulated Köhler curves for SOM particles with dry diameters of 100 nm and using the surface tension of 40 mN m −1 , which is consistent with the surface tension of aqueous mixtures of pinonic acid, pinic acid and pinonaldehyde (Tuckermann and Cammenga, 2004;Hartz et al, 2006). Panel a of Fig.…”

“…The behavior observed here for SOM is consistent with bulk thermodynamics. Consider, for example, a mixture of a relatively hydrophobic organic with a less hydrophobic organic, such as a mixture containing equal mole ratios of heptanol and propanol (Stoicescu et al, 2011). Under dry conditions this mixture exists as a single phase.…”

“…The formation of two phases is due to the non-ideality of the mixture; i.e., if the mixture was ideal, LLPS would not be observed. Examples of other organic mixtures that exhibit this type of behavior include mixtures of hexanol and acetic acid (Senol et al, 2004) and mixtures of octanol and acetone (Tiryaki et al, 1994). For a long list of organic mixtures that undergo liquid-liquid phase separation when mixed with water, see Table 1 in Ganbavale et al (2015).…”

Abstract. Particles consisting of secondary organic material (SOM) are abundant in the atmosphere. To predict the role of these particles in climate, visibility, and atmospheric chemistry, information on particle phase state (i.e. single liquid, two liquids, solid and so forth) is needed. This paper focuses on the phase state of SOM particles free of inorganic salts produced by the ozonolysis of α-pinene. Phase transitions were investigated both in the laboratory and with a thermodynamic model over the range of < 0.5 % to 100 % relative humidity (RH) at 290 K. In the laboratory studies, a single phase was observed from 0 to 95 % RH while two liquid phases were observed above 95 % RH. For increasing RH, the mechanism of liquid–liquid phase separation (LLPS) was spinodal decomposition. The RH range at which two liquid phases were observed did not depend on the direction of RH change. In the modelling studies at low RH values, the SOM took up hardly any water and was a single organic-rich phase. At high RH values, the SOM underwent LLPS to form an organic-rich phase and an aqueous phase, consistent with the laboratory studies. The presence of LLPS at high RH-values has consequences for the cloud condensation nuclei (CCN) activity of SOM particles. In the simulated Köhler curves for SOM particles, two local maxima are observed. Depending on the composition of the SOM, the first or second maximum can determine the critical supersaturation for activation. The presence of LLPS at high RH-values can explain inconsistencies between measured CCN properties of SOM particles and hygroscopic growth measured below water saturation.

“…The separation of aromatic hydrocarbons from alkanes by (liquid + liquid) extraction has been an area of active research [1][2][3][4][5][6][7][8][9][10][11][12][13]. The search for suitability of new solvents, from practical and economical aspects, in (liquid + liquid) extraction is an ongoing investigation.…”
