    High-temperature mutual solubilities of hydrocarbons and water. Part I: Benzene, cyclohexane and n-hexane (1983)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 29 (1983), S. 990-999 
    Details
    ISSN: 0001-1541

    Topics: Chemistry and Pharmacology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: The mutual solubilities at the three-phase equilibrium pressure of three C6 hydrocarbons (benzene, cyclohexane and n-hexane) and water have been experimentally investigated up to 482 K. A thermodynamic analysis of these new measurements and of critically selected literature data has been carried out to the three-phase critical end point. Information is also provided on the two-phase critical locus. The solubility of hydrocarbons in water has been used to calculate Henry's constants, while the solubility of water in the hydrocarbons has been correlated with a modified version of the Redlich-Kwong equation of state. Consideration is also given to the effect of pressure on the mutual solubilities.

    High-temperature mutual solubilities of hydrocarbons and water. Part II: Ethylbenzene, ethylcyclohexane, and n-octane (1985)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 31 (1985), S. 376-384

    Notes: In Part I (Tsonopoulos and Wilson, 1983), the mutual solubilities of three C6 hydrocarbons (benzene, cyclohexane, n-hexane) and water were experimentally investigated and, together with critically selected literature data, were correlated up to the three-phase critical end point. The present paper extends this analysis to the mutual solubilities of three C8 hydrocarbons (ethylbenzene, ethylcyclohexane, n-octane) and water, which have been measured at the three-phase equilibrium pressure up to the critical temperatures (568, 561 and 539 K, respectively). A thermodynamic analysis of these new measurements and of available literature data has been performed up to the three-phase critical end point. Information is also provided on vapor-phase equilibrium compositions. The solubility of hydrocarbons in water has been used to calculate Henry's constants, while the solubility and volatility of water in hydrocarbons has been successfully correlated with several modifications of the Redlich-Kwong equation of state.

    Die Struktur des Ubichinons aus Schweineherzen (1958)
    New York, NY : Wiley-Blackwell
    Helvetica Chimica Acta 41 (1958), S. 2343-2357 
    Details
    ISSN: 0018-019X
    Keywords: Chemistry ; Organic Chemistry

    Topics: Chemistry and Pharmacology
    Notes: The isolation in pure form of the ubiquinone from pig heart is described. From 750 kg raw material 37 g of pure crystalline material could be obtained. Its structure has been established as that of a 2,3-dimethoxy-5-methyl-benzoquinone derivative with a vitamin-K2-like isoprenoid side chain of 50 carbon atoms (I). It is proposed to name this compound ubiquinone(50).

    Mutual solubilities of hydrocarbons and water: III. 1-hexene; 1-octene; C10—C12 hydrocarbons (1997)
    Hoboken, NJ : Wiley-Blackwell

    Notes: This article completes the analysis of high-temperature mutual solubilities of hydrocarbons and water. Part I (Tsonopoulos and Wilson, 1983) presented benzene, cyclohexane, and n-hexane, while Part II (Heidman et al., 1985) extended the investigation to ethylbenzene, ethylcyclohexane, and n-octane. Part III presents experimental data up to the three-phase critical end point for C6, C8, and C10 1-alkenes, n-decane, n-butylcyclohexane, m-diethylbenzene, p-diisopropylbenzene, cis-decalin, tetralin, 1-methylnaphthalene, and 1-ethylnaphthalene. The thermodynamic analysis of Henry's constants for hydrocarbons in water is extended to the critical temperature of water, while the solubility and volatility of water in hydrocarbons are successfully correlated with several modifications of the Redlich-Kwong equation of state.
