Question

What is steam distillation?

Answer 1

Heya students !!!!!

⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩⏩

Steam distillation is similar to distillation under reduced pressure even though there is no reduction in the total pressure acting on the solution.

It is used for the separation and purification of a liquid which is appreciably the volatile in steam from non volatile components of a mixture.

The mixture of organic liqui and water boils at a temperature when the sum of the vapour pressure of the organic liquid is P1 and that of water P2, becomes equal to atmospheric pressure that is

P = P1 + P2.

Answer 2

Steam distillation is a separation process that consists in distilling water together with other volatile and non-volatile components. It is often used to separate volatile essential oils from plant material. for example, to extract limonene (boiling point 176 °C) from orange peels.
