Pressure is an important part in distillation because boiling points of different components to be separated depends on pressure, for normal distillation pressure is kept as 1 atmosphere but for components with high boiling points instead of rasing the temperature pressure is lowered till the vapor pressure of the components to be separated, hence the temperature to be raised becomes less, for example in vaccum distillation.

How does operating temperature affect distillation?

Increasing pressure hinders the ability of two fluids with different boiling points to separate. Reducing pressure does the opposite and makes the fluids easier to separate based on boiling point.

How would the temperature be affected if a distillation were performed on the top of a mountain?

The temperature at the top of a mountain is typically colder than at lower altitudes due to the decrease in atmospheric pressure. This can affect the boiling point of the liquids being distilled, leading to different separation efficiencies and potentially longer distillation times. Additionally, the lower atmospheric pressure may require adjustments to the distillation setup to ensure proper operation.


Discuss the advantage of carrying out fractional distillation at a lower pressure?

Carrying out fractional distillation at a lower pressure allows for separation of compounds with closer boiling points. This is because reducing the pressure lowers the boiling points of the compounds, increasing the efficiency of separation. Additionally, lower pressure can reduce the thermal decomposition of sensitive compounds during distillation.


How does low pressure affect distillation?

Lower pressure shifts the boiling point to lower temperatures. Eg. If your ingredience cannot be heated over 60°C you lower the pressure close enough to vacuum (like 200mBar) and the water in your sample evaporetes at lower temperatures. This is not only a rather mild way of distillation, it is also faster than regulation at atmospheric preassure.

What benefit does one obtain by carrying out the distillation under reduced pressure?

Distillation under reduced pressure allows for the separation of compounds with higher boiling points at lower temperatures, preventing thermal degradation. It also helps to increase the efficiency of the distillation process by reducing the energy required for vaporization. Additionally, reduced pressure distillation can improve the purity of the distillate by minimizing side reactions.


What is the function of the safety tube in steam distillation?

The safety tube in steam distillation serves to prevent excessive pressure buildup in the distillation apparatus. It allows any excess steam to escape, preventing potential hazards such as explosion or damage to the equipment.


Does steam distillation obey Raoults law?

Yes, steam distillation follows Raoult's law, which states that the partial pressure of each component in a mixture is proportional to its mole fraction in the mixture and the vapor pressure of the pure component. This law is used to calculate the composition of the distillate obtained through steam distillation.
