azeotropic उदाहरण वाक्य

उदाहरण वाक्य

1. Column stills are frequently used in the production of grain whisky and are the most commonly used type of still in the production of azeotropic mixture of alcohol and water.
2. Because distillation cannot separate the constituents of an azeotrope, the separation of azeotropic mixtures ( also called " azeotrope breaking " ) is a topic of considerable interest.
3. The method of extractive distillation uses a separation solvent, which is generally non-volatile, has a high boiling point and is miscible with the mixture, but doesn't form an azeotropic mixture.
4. Drying can also be achieved by the use of " in situ " desiccants such as molecular sieves, or the use of azeotropic distillation techniques e . g . with a Dean-Stark apparatus.
5. If the graph were replotted for a different fixed temperature, then the total vapor pressure at the azeotropic composition will certainly change, but it is also possible that the composition at which the azeotrope occurs will change.
6. Whereas a single pot still charged with wine might yield a vapor enriched to 40 50 % alcohol, a column still can achieve a vapor alcohol content of 96 %; an azeotropic mixture of alcohol and water.
7. However, careful application also allows removal of a solvent from a sample containing a liquid compound if there is minimal co-evaporation ( azeotropic behavior ), and a sufficient difference in boiling points at the chosen temperature and reduced pressure.
8. More often, this mixture is attained by the cheaper method of mixing fuming sulfuric acid, also known as oleum sulfuric acid containing excess sulfur trioxide and azeotropic nitric acid ( consisting of about 10 percent nitric acid, with the rest being water ).
9. The azeotropic concentrations are unstable operation points, as any small change in temperature will cause a shift in molar concentration through reactivity ratio effects and cause subsequent composition drift . Azeotropic points are most likely to occur in systems where the feed monomers have similar reactivity ratios.
10.
