| The hydrofluoric acid forms an azeotrope with water, and is distilled over steam. |
| This deviation can be caused by the formation of an azeotrope or a very stable hydrate. |
| When the vapour in equilibrium with a liquid mixture has a composition identical to that of the liquid, the mixture is called an azeotrope. |
| Water, ethanol, volatile organic acids, aldehydes, esters, acetals, and ketones, many of them powerfully aromatic, are among the azeotrope components in wines. |
| Except for R-436A and R-436B, others are either azeotrope or near-azeotropes. |
| Some cosolvents like iso-propanol can form an azeotrope with water to lower the mixtures total boiling point temperature and therefore evaporation of water is aided. |
