Design a process for the purification of crude acetone obtained from the industrial production of phenol to obtain at least 99% pure acetone. Take into account the initial impurities in the crude acetone and suggest suitable separation techniques to remove them. Specify the equipment and operating conditions required for your proposed purification process.

An organic compound was synthesized in the laboratory. The compound is known to contain three functional groups - an alcohol, an alkene, and an ester. Using IR spectroscopy, a broad peak was observed in the region between 3200-3400 cm^-1, which indicates the presence of the alcohol group. However, two different peaks were observed in the region between 1640-1680 cm^-1, which could correspond to either the alkene or ester group. Using other spectroscopic techniques such as NMR and mass spectrometry, determine the structure of the compound and identify which peak corresponds to the alkene or ester functional group.
