Meekins 3 6 November 2018 Abstract In this lab, students learned the basic the techniques of Fractional and Simple distillation. The techniques of Fractional and Simple distillation were used to separate a mixture of Cyclohexane and Acetone. Students gained experience in purifying organic chemicals on a “micro” scale. Boiling points were recorded for both techniques and the best method was chosen. Fraction distillation was chosen as the best method for the separation of a mixture containing cyclohexane and acetone. This was so because the boiling points were reasonably close together (<40˚C). Purpose The purpose of this experiment was to learn the fundamentals of Fractional and Simple distillation. Students built a Fractional Distillation and Simple Distillation apparatus to separate a mixture of Cyclohexane and Acetone. The importance and uses of both techniques were stressed to students.

Meekins 4 Background Distillation is a process used to separate a mixture of two liquids with different boiling points. The mixture is heated until the liquid with a lower boiling point begins to evaporate. The evaporating liquid drips into a separate flask, thus separating the now to pure liquids. There are two common distillation techniques used in chemistry, they include simple
