Excess volume data for mixtures of 1-propanol, 1-butanol, 1-pentanol, and 1-hexanol with methylethylketone were determined at 303.15 and 313.15 K. These volumes are negative with 1-propanol and increasingly positive with the higher homologs, suggesting that the structure-making effect of the ketone outweighs the structure-breaking effect in the first mixture of the series while the structure-breaking effect dominates in the other three mixtures. Further, the temperature coefficient of VE was found to be positive in all four mixtures.

Excess volumes of binary mixtures of alcohols in methylcyclohexane have been determined at 30.0 and 40.0 °C, using a modified dilatometer of Brown and Smith. The systems include: (I) 1-propanol – methylcyclohexane, (2) 1-butanol – methylcyclohexane, (3) 1-pentanol–methylcyclohexane, and (4) 1-hexanol–methylcyclohexane. The VE values are found to be positive over the entire range of composition in all the four systems and the values are interpreted on the basis of the structure-breaking effect of methylcyclohexane.

Abstract Dielectric spectra (up to 72 GHz) have been measured at 20 °C for mixtures of methanol and one of the following substances: morpholine, N-methyl morpholine, N-cyano morpholine, pyrrolidine and N-cyano pyrrolidine. The composition dependence of the relaxation parameters shows close similarities for the morpholines and, on the other hand, for the pyrrolidines, which indicates that a structure breaking effect on methanol is exerted by the former but not by the latter group of substances.

Abstract Excess volumes of mixtures of o-dichlorobenzene with acetone, chloroform, carbon tetrachloride, 1,4-dioxane, and tetrahydrofuran have been measured at 293.15 K as a function of composition. The excess volume data have been used to check the one-fluid theory of mixtures with van der Waals's and Guggenheim's equations of state.

Excess volume data for binary liquid mixtures of butylamine with aromatic and aliphatic hydrocarbons were measured as a function of composition dilatometrically at 303.15 and 313.15 K. The hydrocarbons include: benzene, toluene, three isomeric xylenes, hexane, heptane, and octane. The values of VE were found to be positive over the entire range of composition in all the eight systems at both the temperatures. The positive values were ascribed to the break-up of hydrogen bonds in the aggregates of amine by the hydrocarbons.

In a paper read before the Royal Society of Edinburgh (Proc. Roy. Soc. Edin., xxviii., part v., p. 382 (1908); Zeit. phys. Chem., lxiv. 5) I described a new type of concentration cell, in which the one platinum electrode was surrounded by a solution of ·025 molecules of KI containing ·001 molecules of iodine dissolved in absolute alcohol, and the other electrode was surrounded by ·025 molecules of KI and ·001 molecules of iodine, dissolved in water. This cell developed a considerable E.M.F. of ·198 volts at 25° C. in the direction which would transfer the iodine from water to alcohol and potassium iodide from alcohol to water.

Benzene Toluene

The excess volumes of twenty binary mixtures of four aromatic hydrocarbons (benzene, toluene, ethylbenzene, and p-xylene) and five linear alkanols (methanol, ethanol, 1-propanol, 1-butanol, and 1-pentanol) at 20 °C are reported. The excess volume of systems with the same alkanol increases with increasing size and number of substituents on the benzene ring. For systems with the same aromatic hydrocarbon it increases with the length of the alkanols. The dependence of ∆V/φ1ϑ2 values on composition is noticeably asymmetric. Systems with benzene as one of the component show larger ∆V/φ1ϑ2 values than other systems and systems with methanol show different compositional dependence patterns.
