Nitric acid water azeotrope
WebbGeneral example to understand negative azeotrope is that when hydrochloric acid and water forms azeotropic mixture. To note here that boiling point of Hydrogen chloride is 84 °C and that of water is 100 °C, but the azeotropic mixture have the boiling point of 110 °C, which comprises higher than either of its two constituents. WebbWater contents of these azeotropes are 8, 14, and 28.7 wt%, respectively. Accordingly, the n-butyl acetate is the most thermally efficient of these agents. The n-propyl acetate has been used in large installations, in the first stage as solvent for extraction of acetic acid and then as azeotropic entrainer to remove the accompanying
