In chemistry, "'azeotropic distillation "'is any of a range of techniques used to break an azeotrope in distillation.

An azeotrope is a constant-boiling liquid mixture ( to vapor at a certain temp . ) at a certain % for each component.

A list of 15825 binary and ternary mixtures was collated and published by the ACS . An azeotrope databank is also available online through Edinburgh University

:: I know this is a very old thread, but in response to DanielLC, H2O2 and water do not form an azeotrope.

Distillation of the reaction mixture yields a condensate that is high in water content, since water and formic acid form a high boiling azeotrope.
46.
The temperature and composition of the azeotrope is easily predicted from the vapor pressure of the pure components, without use of Raoult's law.

Note that starting to the right of the azeotrope point results in the same stepwise process closing in on the azeotrope point from the other direction.

The azeotrope should also be stable as far as evaporation is concerned, as well as the individual components when they are separate, of course.

Anhydrous magnesium nitrate is also used to increase the concentration of nitric acid past its azeotrope of approximately 68 % nitric acid and 32 % water.
