This dehydration technology can account for energy saving of 3, 000 btus / gallon ( 840 kJ / L ) compared to earlier azeotropic distillation.
32.
Azeotropic mixtures show a pressure maximum / temperature minimum or pressure minimum / temperature maximum that is above / below the values of the pure components.
33.
When an entrainer is added to a binary azeotrope to form a ternary azeotrope, and the resulting mixture distilled, the method is called azeotropic distillation.
34.
I suppose I can do this simply by diluting the HCl to the concentration of the azeotropic mixture ( which I think is 6.102M ).
35.
Pressure-swing distillation is essentially the same as the unidirectional distillation used to break azeotropic mixtures, but here both positive and negative pressures may be employed.
36.
This practice of adding an entrainer which forms a separate phase is a specific sub-set of ( industrial ) azeotropic distillation methods, or combination thereof.
37.
Some techniques achieve this by " jumping " over the azeotropic composition ( by adding another component to create a new azeotrope, or by varying the pressure ).
38.
The reaction can be driven to the acetal when water is removed from the reaction system either by azeotropic distillation or trapping water with molecular sieves or aluminium oxide.
39.
This has now mostly been replaced by the less expensive procedure that uses a nearly 1 : 1 solution of oleum and azeotropic nitric acid ( 70 % ).
40.
To break azeotropic distillations and cross distillation boundaries, such as in the DeRosier Problem, it is necessary to increase the composition of the light key in the distillate.
