Solubility of water in individual hydrocarbons

Apparatus for the Determination of Water Solubility in Hydrocarbon: Toluene and Alkylcyclohexanes (C6 to C8) from 30 °C to 180 °C

“…The validation of our apparatus is based on comparison of these values with the literature data. Our experimental value at 30°C {(3.30 ( 0.03) × 10 -3 } is in good agreement with the (3.14 × 10 -3 ) value obtained by Englin et al 7 Figure 2 shows good agreement between the literature data and our values, which validates our method and demonstrates the capability and the reliability of our technique for the determination of the solubility of water in a hydrocarbon. As expected, increasing temperature increases the mole fraction solubility of water in toluene.…”

Mutual solubilities of hydrocarbons and water: III. 1‐hexene; 1‐octene; C10C12 hydrocarbons

“…The water solubility in p-diisopropylbenzene is not shown because it essentially coincides with the water solubility in m-diethylbenzene. Again, the data of Guerrant (1964) for m-diethylbenzene are inconsistent with our data, while the low-temperature data of Englin et al (1965) for water in diethylbenzene (unspecified isomer) are higher than our data. RKS is the most accurate EoS for the water solubility in nbutylcyclohexane, while RKJZ is the most accurate for the water solubility in m-diethylbenzene and p-diisopropylbenzene (not shown in Figure 11).…”

“…The solubilities of water in 1-butene (Leland et al, 1955;Wehe and McKetta, 1961), 1-hexene and 1-decene are very similar, except as their T3c is approached. The experimental data of Budantseva et al (1976) for 1-hexene at 20"C, and those of Englin et al (1965) for 1-hexene at 30°C (not shown here) and for 1-octene (shown in Figure 9) appear to be inconsistent with the new data. RKJZ is the most accurate EoS for the correlation of water solubility in all four 1-akenes.…”

“…The data for l-ethylnaphthalene nearly coincide with those of 1-methylnaphthalene and are not shown for clarity. The limited data available in the literature for these hydrocarbons are those of Englin et al (1965) for water in 1-methylnaphthalene and decalin at low temperature; Guerrant (1964) for water in cis-decalin at 574.8 K and Christensen and Paulaitis (1992) at 573.15 K for water in tetralin and 1-methylnaphthalene. Figure 12 shows that the temperature dependence of the water solubility in tetralin is not consistent with that in other two-ring hydrocarbons.…”
