Definition of azeotrope in English:

azeotrope

noun əˈziːətrəʊpˈeɪzɪətrəʊpeɪˈziəˌtroʊp

Chemistry

A mixture of two liquids which has a constant boiling point and composition throughout distillation.
〔化〕共沸（混合）物，恒沸物
Example sentencesExamples
- Ethyl acetate and ethanol form azeotropes - liquids whose boiling point, and hence composition, does not change as vapour escapes on boiling.
- The principal volatile components of wine tend to form azeotropes of two, three, or more components.
- The industrial use of azeotropes to distill or purify mixtures of liquids is one of the more important aspects in any distillation process.
- Little did these early distillers know that ethyl alcohol and water form a mixture called an azeotrope which cannot be purified past a certain point by traditional distillation methods.
- An azeotrope is a mixture with a constant boiling point that cannot be separated by distillation.

Derivatives

azeotropic

adjectiveəˈziːətrəʊpɪkeɪzɪəˈtrəʊpɪkˌeɪˌziəˈtrɑpɪk

Chemistry

Acetaldehyde, acetic acid, ethyl acetate and the fusel oils all tend to form azeotropic mixtures with the water and ethanol of the wine.
Example sentencesExamples
- Azeotropes or azeotropic mixtures occur for a number of important chemical compounds but perhaps the most important is the ethanol-water mixture.
- An azeotropic distillation was used to extract the water.
- The samples were refluxed for 24 h in an azeotropic mixture of dichloromethane and methanol.
- To prevent fraud, chemists measure the moisture content of the spice using azeotropic distillation to detect the possible addition of water, which can be added in an attempt to increase an oil's perceived value.

Origin

Early 20th century: from a-¹ 'without' + Greek zein 'to boil' + tropos 'turning'.
