Q1. What is vacuum distillation? How to create vacuum?
Ans. 
Vacuum distillation is a process of separating components of a mixture by boiling it under reduced pressure.
• It is used to separate components with high boiling points.

• The process involves heating the mixture in a vacuum to lower the boiling point.

• The lower pressure also reduces the risk of thermal decomposition.

• Vacuum can be created using a vacuum pump or aspirator.

• Examples include the separation of crude oil into diff...read more

Q2. Type of distillation?
Ans. 
There are various types of distillation methods such as simple distillation, fractional distillation, steam distillation, vacuum distillation, etc.
• Simple distillation is used to separate liquids with different boiling points

• Fractional distillation is used to separate liquids with similar boiling points

• Steam distillation is used to extract essential oils from plants

• Vacuum distillation is used to distill high boiling poi...read more

Q3. Which type packing is batter in distillation continue?
Ans. 
The type of packing that is better in distillation depends on the specific application and desired outcome.
• Structured packing is better for high efficiency and low pressure drop

• Random packing is better for high capacity and fouling resistance

• Trays are better for high turndown ratio and easy maintenance

• Factors to consider include composition of the mixture, desired separation efficiency, pressure drop limitations, and c...read more

Q1. What is the density, vaccum, how to create vaccum 760 mmhg in reactor
Ans. 
To create a vacuum of 760 mmHg in a reactor, the density of the substance inside must be reduced.
• Reduce the density of the substance inside the reactor by removing any gases or liquids that may be present.

• Use a vacuum pump to remove any remaining gases or liquids and create a vacuum.

• Ensure that the reactor is properly sealed to maintain the vacuum.

• Monitor the pressure inside the reactor to ensure that it remains at 760...read more

Q1. Boiling point of solvent
Ans. 
The boiling point of a solvent depends on its chemical composition.
• The boiling point of a solvent is the temperature at which it changes from a liquid to a gas.

• Solvents with stronger intermolecular forces have higher boiling points.

• For example, water has a boiling point of 100°C, while acetone has a boiling point of 56°C.

• The boiling point can also be affected by external factors such as pressure.

• Knowing the boiling poi...read more
