Abstract

The phase equilibrium of the cyclohexane2,2,4-trimethylpentane system was established over the entire range of composition by cooling curve analysis. There is a eutectic at -113.95 degrees and a mole fraction of cyclohexane of 0.25. The phase transition for cyclohexane (solid I to 11) is at -87.06 degrees and the break in the solubility curve comes at a mole fraction of cyclohexane of 0.65. The calculated ideal solubility of cyclohexane is close to the experimental solubility, confirming the nearly ideal behavior that this system exhibited in other studies. A new cooling curve apparatus is described.
