This is an incredibly complex azeotrope.

However, the higher pressure and the fact that the fluid is almost an azeotrope provide an opportunity to design more compact systems with greater efficiency.

The temperature alteration during phase change is commonly called "temperature glide." An intermediate class of mixtures, dubbed "near-azeotropes," are really zeotropes that are close to an azeotropic composition and have a very small temperature glide.

In distillation, an azeotrope cannot be separated into its individual components.

When distilling liquids, it is important to identify an azeotrope, as it behaves differently than regular mixtures.

Etymology
Azeotrope comes from Greek parts a- 'not', zeō 'to boil', and -trope 'turn', and the -trope part is like in tropic meaning 'turn'. So an azeotrope is a mix of liquids that 'does not change when boiled', which is why it cannot be separated by simple distillation.
