Density of supercooled aqueous solutions of alcohols

Conclusions

  1. 1.

    The specific volumes of aqueous solutions of three alcohols were determined at the temperatures 0 to −40°.

  2. 2.

    The dependences of the specific volumes on the concentration of solutions of isopropyl and tert-butyl alcohols at temperatures below −20° have a maximum and a minimum.

  3. 3.

    For most aqueous solutions at temperatures below 4°, the difference between the specific volume of pure water and its partial specific volume in solution increases with decreasing temperature.

  4. 4.

    For solutions of isopropyl and tert-butyl alcohols in a limited range of concentrations and temperatures, the opposite effect is observed.
