Density, surface tension and refractive index of aromatic hydrocarbons at low temperatures

  • 189 Accesses

Summary

  1. 1.

    The temperature dependence of the density and refractive indices of ethylbenzene, o- and m-xylenes from 273° K down to their crystallization temperatures has been investigated. This dependence has been shown to be linear.

  2. 2.

    The temperature dependence of the surface tension of toluene, ethylbenzene, o- and m-xylenes is linear from 273° K down to their crystallization temperatures.

  3. 3.

    Hydrostatic weighing gives reliable results for determining the densities of the liquids at low temperatures.

  4. 4.

    The molecular refraction and parachor of toluene, ethylbenzene, m-xylene and o-xylene have a tendency to decrease with a decrease in temperature from 273° K.
