Separations and purifications: Creating and separating acetone


Acetone is the active ingredient in nail polish remover and is ubiquitous in chemistry laboratories. Most laboratories order acetone in bulk not only for cleaning glassware, but also for use as a chemical reagent. One method for producing acetone is shown below
Figure 1. Creating acetone using benzene and propene as reactants.
Acetone can also be produced from the decarboxylation of acetoacetic acid. At temperatures above 0°C, acetoacetic acid spontaneously decomposes as shown in the following reaction.
Figure 2. Creating acetone through decarboxylation of acetoacetic acid.
To isolate the products of these reactions, different techniques for separation and purification were utilized. The boiling points of some of these chemicals along with other common reagents are shown in the following table.
