1. Plural of azeotrope; mixtures of two or more liquids that boil at a constant temperature and maintain a constant composition in both the liquid and vapor phases.
Usage: chemistry; technical term; also called azeotropic mixtures

Examples

• Ethanol and water form one of the most well-known azeotropies in chemistry.
• The azeotropies of certain solvent mixtures make them difficult to separate by simple distillation.
• Engineers must account for azeotropies when designing distillation columns for industrial processes.
• Different azeotropies have different boiling points depending on their composition.
• The study of azeotropies is essential in chemical engineering and laboratory practice.
