Question

What is the principle of evaporation?

Answer 1

Explanation:

• Evaporation is a process of solvent removal from the solution by “boiling the liquid” in a solvent.

• And it is very suitable from the solution where the boiling of the liquid in “suitable vessel and withdrawing” of the vapour leaving from the concentrated product.

• A solid substance that has dissolved in a liquid is separated by evaporation.
• It is based on that fluids are readily vaporising while solids are not readily vaporising.

Applications:

• Evaporation process is useful for manufacturing of the bulk drugs.

• Evaporation process is very much helpful in the manufacture of “biological products” such as Enzyme, Insulin and Hormones.

Answer 2

Evaporation is used to separate the components of a homogenous solid-liquid mixture in which the solid is recovered while the liquid escapes in the form of vapor. This is the principle of evaporation.
