Phase Diagrams of the Three-Component System n-Decane–n-Octadecane–Cyclododecane

Аннотация

The phase equilibrium of the three-component n-decane-n-octadecane-cyclododecane system in the temperature range from −50 to 70°С is studied via differential thermal analysis. It is established that the investigated system is of the eutectic type. The eutectic composition is 84.5 wt % n-С₁₀Н₂₂, 5.5 wt % n‑С₁₆Н₃₄, and 10.0 wt % С₁₂Н₂₄. It has a melting point of −35.0°C. The obtained data could be of interest to researchers in the field of the thermodynamics of phase equilibria.
