 (ə-zē′ə-trōp′, ā′zē-)
A liquid mixture of two or more substances that boils at a constant characteristic temperature lower or higher than any of its components and that retains the same composition in the vapor state as in the liquid state.

[a- + Greek zein, to boil; see zeolite + Greek -tropos, turning; see -tropous.]

a′ze·o·trop′ic (ā′zē-ə-trŏp′ĭk, -trō′pĭk) adj.
a′ze·ot′ro·py (-ŏt′rə-pē) n.


(Elements & Compounds) a mixture of liquids that boils at a constant temperature, at a given pressure, without change of composition
[C20: from a-1 + zeo-, from Greek zein to boil + -trope]
azeotropic adj


(əˈzi əˌtroʊp, ˈeɪ zi-)
any liquid mixture having constant minimum and maximum boiling points and distilling off without decomposition and in a fixed ratio.
[1910–15; a-6 + Greek zé(ein) to boil + -o- + -trope]
a•ze•o•trop•ic (ˌeɪ zi əˈtrɒp ɪk, -ˈtroʊ pɪk) adj.


(azeotropic mixtures) A mixture of liquids which boils without a change in composition. When it boils it gives off a vapor whose composition is the same as the liquid.
