Difference Between Evaporation and Distillation

Rotary evaporator is most commonly used when you want to remove a solvent. The liquid deposits a film on almost the entire surface of the flask. This film allows for a large surface area and the liquid evaporates faster. This method of removing a solvent is most commonly used when you want to remove a lot of solvent. Short path distillation is often used for compounds which …

The advantage is that the heating temperature can be considerably lower at reduced pressure than the boiling point of the liquid at standard pressure, and the distillate only has to travel a short distance before condensing. A short path ensures that little compound is lost on the sides of the apparatus. Rotary Evaporation
