Aldol Condensation Author: T.A. Forrest Helfrich Date Performed: February 26 th 2007 Date Submitted: March 5 th 2007 Abstract: In this experiment, the purpose was to perform a double aldol condensation. By examining the results from the experiments, it was found that this did take place between the p-tolyaldehyde and the acetone. The melting point for the product was found to be 176 degrees. The percentage of the crude product obtained was 53.89% and the final product was 44.69%. The IR spectrum showed that of both acetone and p_tolyaldehye as well as the NMR.

Introduction In this experiment, the purpose is to perform a double aldol condensation. Then the dehydration product will be isolated, recrysallized from a suitable solvent and analyzed by IR and NMR spectroscopy. Each student will be assigned an aldehyde and a ketone. It will be necessary for each student to find the appropriate solvent for their specific substances. It is possible that the students might need to try their product in every solvent provided.
