TL;DR: In this article, the Abraham solvation equations are used to predict further partition coefficients, and also provide information on the chemical features of the various systems, such as the hydrogen bond basicity of dry tetrahydrofuran and dry dioxane.
Abstract: Equations based on the Abraham solvation equations are presented for the partition of solutes between water and wet diethyl ether, wet diisopropyl ether, dry diethyl ether, dry diisopropyl ether, dry tetrahydrofuran and dry dioxane, and between the gas phase and wet diethyl ether, dry diethyl ether, dry tetrahydrofuran and dry dioxane. These equations can be used to predict further partition coefficients, and also provide information on the chemical features of the various systems. It is shown that wet diethyl ether is more basic and less hydrophobic than dry diethyl ether, although the differences are quite small. The hydrogen bond basicity of dry tetrahydrofuran and dry dioxane is about the same as that of wet diethyl ether and wet diisopropyl ether, and their hydrophobicity is between that of wet and dry diethyl ether.

TL;DR: In this article, the interaction of chlorohydridotris(triphenylphosphine)ruthenium(II) with NaOH or KOH in tetrahydrofuran, acetone, or t-butyl alcohol leads, depending on conditions, to red, five-coordinate complexes RuH(OH)(PPh3)2(sol)(sol = thf or H2O) secondly to hydroxo-bridged dimers, and thirdly to a tetranuclear complex of stoicheiometry Ru4H4(OH
Abstract: The interaction of chlorohydridotris(triphenylphosphine)ruthenium(II) with NaOH or KOH in tetrahydrofuran, acetone, or t-butyl alcohol leads, depending on conditions, first to red, five-co-ordinate complexes RuH(OH)(PPh3)2(sol)(sol = thf or H2O) secondly to hydroxo-bridged dimers, (PPh3)2H(sol)Ru(µ-OH)2Ru(sol)H(PPh3)2(sol = Me2CO, H2O, or ButOH) and thirdly to a tetranuclear complex of stoicheiometry Ru4H4(OH)2(PPh2)2(CO)2(PPh3)6(Me2CO)2.Interaction of dichlorotris(triphenylphosphine)ruthenium(II) with KOH gives similar compounds, RuCl(OH)(PPh3)2(sol)2 and {RuCl(OH)(PPh3)2(sol)}2(sol = H2O or thf) as well as {RuH(OH)(PPh3)2(thf)}2.The interaction of RuHCl(PPh3)3 with sodium methoxide gives rise to two compounds that are formulated, respectively as having Ru–CHO and Ru–OCH2 groups, The mechanism of decarbonylation of alcohols is discussed and the compounds RuH2(CO)(PPh3)2·ROH (R = Me or Et) are synthesised.I.r. and 1H and 31P n.m.r. spectra of the various complexes are given and structures for the compounds proposed on this basis.

TL;DR: In this article, the authors determined the SE for polymers on inorganic solids from adsorption/desorption transitions in binary solvent mixtures which were measured by thin layer chromatography.
Abstract: Segmental adsorption energies for polymers on inorganic solids were determined from adsorption/desorption transitions in binary solvent mixtures which were measured by thin layer chromatography. Polystyrene, poly(methyl methacrylate), poly(butyl methacrylate), poly(tetrahydrofuran) and poly(ethylene oxide) were classified according to their adsorption strength on silica and alumina. A consistent trend with respect to the adsorption energy was observed for both substrates.
