IUPAC-NIST Solubility Data Series. 81. Hydrocarbons with Water and Seawater—Revised and Updated. Part 4. C6H14 Hydrocarbons with Water

The mutual solubility and related liquid-liquid equilibria of C 6H14 hydrocarbons with water are exhaustively and critically reviewed. Reports of experimental determination of solubility in five chemically distinct binary systems that appeared in the primary literature prior to end of 2002 are compiled. For all five systems sufficient data are available to allow critical evaluation. All data are expressed as mass percent and mole fraction as well as the originally reported units. In addition to the standard evaluation criteria used throughout the Solubility Data Series, a new method based on the evaluation of the all experimental data for a given homologous series of saturated or unsaturated aliphatic hydrocarbons was used.

IUPAC-NIST solubility data series. 81. Hydrocarbons with water and seawater-revised and updated. Part 5. C7 hydrocarbons with water and heavy water

The mutual solubility and related liquid-liquid equilibria of C7 hydrocarbons with water and heavy water are exhaustively and critically reviewed. Reports of experimental determination of solubility in 23 chemically distinct binary systems that appeared in the primary literature prior to end of 2002 are compiled. For 9 systems sufficient data are available to allow critical evaluation. All data are expressed as mass percent and mole fraction as well as the originally reported units. In addition to the standard evaluation criteria used throughout the Solubility Data Series, a new method based on the evaluation of the all experimental data for a given homologous series of aliphatic and aromatic hydrocarbons was used.

IUPAC-NIST Solubility Data Series. 81. Hydrocarbons with Water and Seawater—Revised and Updated. Part 2. Benzene with Water and Heavy Water

The mutual solubilities and related liquid-liquid equilibria of benzene with water and heavy water are exhaustively and critically reviewed. Reports of experimental determination of solubility in these two chemically distinct binary systems that appeared in the primary literature prior to end of 2002 are compiled. For the system benzene-water sufficient data are available to allow critical evaluation. All data are expressed as mass percent and mole fraction as well as the originally reported units. In addition to the standard evaluation criteria used throughout the Solubility Data Series, a new method based on the evaluation of all experimental data for a homologous series of aromatic hydrocarbons was used.

Application of hard convex body and hard sphere equations of state to the critical properties of binary mixtures

Abstract The critical properties of hydrocarbon mixtures, perfluorocarbon + hydrocarbon, perfluoromethylcyclohexane + siloxane, acetone + hydrocarbon and polydimethyl siloxane mixtures have been calculated from an equation of state for hard convex bodies and from Guggenheims equation of state for hard spheres. In general, the results of both equations agree well with experimental data. It appears, however, that taking shape factors into account (by using the hard convex body equation) does not lead to a significant improvement in the agreement between theory and experiment for the critical properties.

Critical properties of ternary mixtures: hydrocarbon, acetone and alkanenitrile mixtures

Abstract The critical temperatures of several ternary mixtures containing hydrocarbons, acetone, acetonitrile and propylcyanide are reported. A Newton-Raphson procedure and a general solution for solving the criticality conditions of ternary mixtures using the one-fluid model and the Guggenhiem equation of state are outlined. The critical temperatures of the three related binary mixtures were used to obtain the three unlike interaction parameters so that no additional parameters were needed to calculate the critical temperatures of the ternary mixtures. Agreement between experiment and theory is, in general, quite good.

Phase behaviour of fluorocarbon and hydrocarbon mixtures: interpretation of type II and type III behaviour in terms of a ‘hard-sphere + attractive force’ equation of state

Abstract Christou, G., Morrow, T., Sadus, R.J. and Young, C.L., 1986. Phase behaviour of fluoro-carbon and hydrocarbon mixtures: interpretation of type II and type III behaviour in terms of a ‘hard-sphere + attractive force’ equation of state. Fluid Phase Equilibria , 25: 263–272. Experimental measurements of the upper critical solution temperature of octadecafluorooctane + n -alkanes are reported. These measurements and those discussed by Schneider (1983) on the phase behaviour of tetrafluoromethane + alkanes are compared with results obtained from the one-fluid model using a ‘hard sphere + attractive term’ equation of state. Interaction parameters, ξ, obtained from the comparison together with values from the literature on other fluorocarbon + hydrocarbon mixtures show trends which are briefly discussed.

IUPAC-NIST Solubility Data Series. 103. Oxygen and Ozone in Water, Aqueous Solutions, and Organic Liquids (Supplement to Solubility Data Series Volume 7)

This volume is an update of the Solubility Data Series Volume 7 published in 1981 on oxygen and ozone. For this volume, the literature was covered from 1981 to 2009 with some papers from 2010. Some earlier papers missed in the 1981 volume are included. Interest in the solubility of oxygen and of ozone continues to be high. The solubility of oxygen in water at low pressure seems well established, but more work is needed on the solubility of oxygen in water at high pressure and high temperature. There is now a wealth of salt-effect data on the solubility in aqueous salt solutions, but some glaring discrepancies still exist. Little has been done on salt effects at high pressure and high temperature. The solubility data of oxygen in hydrocarbons seem sparse. The solubility of oxygen in alcohols through C5 seems well established. Between the 1981 volume and this volume, there are solubility data in over 70 fluorocarbons and fluorocarbon compounds with O, H, S, and N. A new area is the solubility of oxygen in ionic liquids, which are becoming increasingly important as replacement solvents for volatile organic solvents. Information on the solubility of ozone in water, aqueous solutions and organic liquids has also been updated.

Gas-liquid critical temperatures of mixtures containing electron donors II. Amine mixtures

Abstract The gas-liquid critical temperatures of mixtures of alkanes, aromatic hydrocarbons, hexafluorobenzene, and tetrachloromethane with some ethers have been measured. The strength of the interaction between pairs of unlike molecules in the mixture have been estimated from the results using the one-fluid model and an equation of state which incorporates a hard-sphere term and an attractive term. It is concluded that there may be a small enhanced interaction between the ethers and aromatic hydrocarbons or aromatic fluorocarbons. Analysis of the critical temperatures indicates that enhanced interactions are very small for aliphatic ethers and slightly larger, but still small, for cyclic ethers: tetrahydrofuran, and 1,4-dioxan.

Critical properties of ternary mixtures: Siloxane and perfluoromethylcyclohexane mixtures

Abstract The critical temperatures of some ternary siloxane mixtures are reported. The critical temperatures of binary perfluoromethylcyclohexane and siloxane mixtures were also measured. The results are compared to values calculated by solving the critical conditions from conformal solution theory using the one-fluid model, the ideal mixing equation and the Guggenheim equation of state. The agreement is good for mixtures of similar sized molecules whereas the agreement for dissimilar sized molecules is somewhat inadequate.

Phase behaviour of binary n-alkanenitrile and n-alkane, and nitromethane and alkane mixtures

Abstract Upper critical solution temperatures of nitromethane and alkanes, and alkanenitriles and alkanes have been used to obtain a parameter, ψ, characterising the interaction between the pairs of unlike molecules in the mixture. Values of ψ have been calculated using a “hard sphere and attractive force” equation of state together with the van der Waals one fluid model. Values of ψ obtained for the ethanenitrile and alkane mixtures have been compared with those obtained from an analysis of gas—liquid critical temperatures. There is a discrepancy of several percent between the values calculated from the two properties.
