文摘

Solid−liquid equilibria have been measured for binary mixtures of 1,8-cineole with p-cymene, β-pinene, and camphene, respectively, using differential scanning calorimetry (DSC) over the whole composition concentration range. All three are simple eutectic systems. The eutectic point of the (1,8-cineole (1) + p-cymene (2)) mixture is at 200.0 K and x₁ = 0.124, the (1,8-cineole (1) + β-pinene (2)) mixture at 205.6 K and x₁ = 0.154, and the (1,8-cineole (1) + camphene (2)) mixture at 251.8 K and x₁ = 0.582. An empirical equation of Ott and Goates was used for correlating the experimental data.
