Conclusion Fractional Distillation and Purification of Acetone The purpose of this experiment was to establish an understanding for the basic underlying principles in fractional distillation as well as learn the proper procedures for distillation and set up of a macro distillation kit. Using a known liquid which contained impurities, a distillation apparatus (Notebook pg. 30) was set up in order to purify the acetone. By taking the mass of the distillate collected and dividing it by the mass of the original sample, followed by multiplication of 100 gives the Percent Composition of the original acetone. The procedure involved setting up a fractional distillation apparatus using a round-bottom flask as the “pot” and a graduated cylinder as a receiver for the distillate. The pot was heated by a variac at ~35% of the heating mantle’s original power (a magnetic stir bar was used to prevent bumping). The pot was brought to a slow boil and a vapor front began to rise up the fractional
