azeotropic distillation is any of a range of techniques used to break an azeotrope in distillation. In chemical engineering, azeotropic distillation usually...

adding sodium chloride in a process known as salting out. It forms an azeotrope with water, resulting in a boiling point of 80.37 °C and is characterized...

Azeotrope is Seattle-based theatre company specializing in new work that focuses on bringing voice and representation to the marginalized and invisible...

Purification cannot be performed by simple distillation due to formation of an azeotrope with water, although initial drying of the solvent containing large amounts...

production is still in use today. Commercially available nitric acid is an azeotrope with water at a concentration of 68% HNO3. This solution has a boiling...

in the pure liquid. An example is the azeotrope of approximately 95% ethanol and water. Because the azeotrope's vapor pressure is higher than predicted...

ordinary distillation practices due to the ethanol and water becoming an azeotrope mixture) and is not aged or flavored before being diluted with water to...

Furthermore, polyesters are accessible via ring-opening polymerization. Azeotrope esterification is a classical method for condensation. The water formed...

hydroiodic acid usually contains 48–57% HI by mass; the solution forms an azeotrope with boiling point 126.7 °C (260.1 °F) at 56.7 g HI per 100 g solution...

hydrogen-bonded formic acid molecules. Formic acid forms a high-boiling azeotrope with water (107.3 °C; 77.5% formic acid). Liquid formic acid tends to...

binary (two-component) mixture of HCl and H2O has a constant-boiling azeotrope at 20.2% HCl and 108.6 °C (381.8 K; 227.5 °F). There are four constant-crystallization...

high-boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture. The method is used for mixtures...

the KHSO4 and by distilling off the water until the solution reaches an azeotrope (124.3 °C). The yield is approximately 85%. Hydrobromic acid is available...

is about 97.2% ABV (194.4 proof) because at that point alcohol is an azeotrope with water. A spirit which contains a very high level of alcohol and does...

maximum-boiling azeotropes, where the azeotrope temperature is at a maximum in the boiling curves, or minimum-boiling azeotropes, where the azeotrope temperature...

from two ethanol molecules to create diethyl ether, which also forms an azeotrope with ethanol, and therefore distils with it. The result is a sweeter spirit...
