distillation involves a mixture of substances, boiling and separating one of those. Sublimation is one single substance like iodine changing from a solid to a gas without going thru the liquid phase.
i want to know about pressure distillation
Two liquids in a mixture with different boiling points can be separated by distillation.
No; also filtering and distillation are different processes.
Different in volatility.
Fractional distillation is applied when many components exist an the differences between boiling points are under 25 oC.
Distillation. By applying heat to the mixture it will boil, but the different liquids within the mixture will boil or vapourise at different temperatures. This means that the different vapours can be drawn off at different stages and then condensed back into liquid form. One example of where this is used on an industrial scale is at a oil refinery. The crude oil extracted from oil fields is heated in large distillation towers. These then separate out different products from heavy oil (higher boiling point), through to petrol (medium boiling point) to propane (low boiling point).
Homogeneous mixtures can only be separated by distillation if their components have significantly different boiling points. If the components have similar boiling points, distillation may not be an effective method for separation.
Fractional distillation
Distillation Filtration Evaporation
DISTILLATION
This is known as a distillation. Ethanol and water can be separated using this process because their boiling points are different which allows them to be "boiled off" at different temperatures.
A distillation temperature chart provides information about the boiling points of different substances in a mixture, helping to determine the separation and purity of components during distillation.
