English Dictionary

azeotrope

名詞

(physics) A mixture of two or more substances whose liquid and gaseous forms have the same composition (at a certain pressure); the substances cannot be separated by normal distillation.

日本語の意味

（物理学）特定の圧力下で、液体状態と気体状態の組成が同一となる、2種類以上の物質の混合物。通常の蒸留によってそれらを分離することが困難である混合物。

Because ethanol and water form an azeotrope, simple distillation cannot completely separate them at atmospheric pressure.

エタノールと水は共沸混合物を形成するため、常圧での単純蒸留では完全に分離できません。

意味（1）

(physics) A mixture of two or more substances whose liquid and gaseous forms have the same composition (at a certain pressure); the substances cannot be separated by normal distillation.

The formation of azeotropes due to deviations from Raoult's law was discussed in Section 1.3. An azeotrope is a mixture that, at a given pressure (the azeotropic pressure), boils at a constant temperature (the azeotropic temperature), and has the same composition (the azeotropic composition) in the equilibrium vapor and liquid phases. Homogeneous azeotropes are those that form one liquid phase at equilibrium with the vapor; heterogeneous azeotropes are those that form two liquid phases at equilibrium with each other and the vapor.
