Is rotary evaporator distillation?

Is rotary evaporator distillation?

A rotary evaporator is a specially designed instrument for the evapora- tion of solvent (single-stage or straight distillation) under vacuum. The evaporator consists of a heating bath with a rotating flask, in which the liquid is distributed as a thin film over the hot wall surfaces and can evaporate easily. Click to see full answer.

Differences between Evaporation and Distillation

Differences between Evaporation and Distillation

Apr 05, 2022 The liquid is heated to produce the gaseous state of the liquid after which the obtained gas form is produced into its proper liquid form, free of impurities. Evaporation is a very slow and gradual process. Distillation is a very fast and rapid process. Evaporation occurs mostly only on the surface. Distillation occurs throughout the whole liquid.

The evaporation capacity of a rotary evaporator is about 4 times greater than that of a conventional, static distillation apparatus. Heat transmission in the heating bath as well as inside the flask is greatly improved by rotation of the evaporating flask. Rotation greatly enlarges the active surface inside the flask, hastening the evaporation.
