The purpose of this laboratory experiment was to fractionally distill waste acetone from last semester using a self-prepared apparatus in order to purify it back into pure acetone, as well as to learn how to use a refractometer to obtain a refractive index of our purified acetone and compare that value to a literature value to determine if the compound was indeed acetone.

An experimental flaw could have been that the waste acetone had compounds in it that lowered the boiling point of the mixture, resulting in a lower boiling point. Another reason could be the differenA demonstration of several distillation techniques (simple distillation, fractional distillation and steam distillation) used in Organic Chemistry labs.Demonstrations conducted by:Dr.

James 5 Conclusion: From the chart it appears that the fractional distillation was slightly more efficient than the simple distillation. The simple distillation graphed basically as a straight line, but the graph of the fractional distillation actually, to a certain degree, shows a plateau.
