Distillation I: Simple Fractional Distillations

Distillation I: Simple Fractional Distillations

A heating mantle, which is plugged into the Variac, rests on an iron ring below the distilling flask. If you're using a stir bar, then place a magnetic stirrer underneath the heating mantle. Leave enough room below the iron ring so that the heating mantle can be dropped away from the distilling flask if necessary.

Distillation is a technique that is used to purify a mixture of liquids or to obtain a boiling point of a pure liquid (in the case of this course). Essentially, the liquid is heated to boiling and the vapors condensed above the boiling liquid. Apparatus. This is a 4.5 minute movie on how to set up a simple distillation apparatus.

into the heating mantle and working outwards toward the receiving flask. In order to select your flask size, remember that the flask should only be about 2/3 full of the liquid to be distilled. It is useful to support the heating mantle on a wooden block or an iron ring so that heating may be discontinued immediately.

purity. Each vaporization-condensation step is known as a “simple distillation”. Thus, for this mixture, three simple distillations have produced the desired purification. Fractional Distillation. Unfortunately, each time a distillation is run, material is lost. Some evaporates into the air and some is left behind, stuck to the apparatus.
