A large number of normal or nearly normal liquids were investigated in a search for pairs that would not be completely miscible. Aniline and hexane proved to furnish the nearest approach to the desired conditions. The following properties were investigated: mutual solubility, vapor pressure, heat of mixing, surface tension, change of volume on mixing, and compressibility. It has been shown that there is a strong positive deviation of the vapor pressure from Raoult's law, that the formation of mixtures is accompanied by an absorption of heat, by an expansion for mixtures rich in hexane and a contraction for those rich in aniline, that the surface tension of the mixture is less than additive, and that the compressibility of a mixture rich in hexane is greater than additive, while that of one rich in aniline is less than additive. The theoretical bearing of the foregoing facts has been discussed briefly. © 1917, American Chemical Society. All rights reserved.
