WebAzeotropes are a mixture of at least two different liquids. Their mixture can either have a higher boiling point than either of the components or they can have a lower boiling point. … Web11 nov. 2024 · It is also known as an azeotropic mixture or constant boiling point mixture. Azeotropy occurs when a mixture is boiled to produce a vapor that has the same composition as the liquid. The term is derived by combining the prefix "a," meaning "no," and the Greek words for boiling and turning.
