Azeotropes
- Azeotropes are binary mixturespossessing the same synthesis in fluid, vapor stage and boiling stage at a steady temperature.
- The components of azeotropic mixtures are separated by fractional distillation.
- Azeotropes can be broadly categorized into two types-
- Minimum boiling azeotrope
The solutions showing positive deviation from Raoult’s law. For instance, solution of ethanol and water on fractional distillation results in a solution containing approximately 95% by volume of ethanol.
- Maximum boiling azeotrope.
The solutions showing negative deviation from Raoult’s law. For instance, solution of nitric acid and water has the approximate arrangement, 68% nitric corrosive and 32% water by mass, with a breaking point of 393.5 K.
