Experiment 15: Diels-Alder Reaction: 9,10-Dihydroanthracene-9,10-α,β-succinic Acid AnhydrideObjective:The purpose of this lab was to investigate the Diels-Alder reaction involving an aromatic ring system as the diene reacts with a dienophile. This reaction is a 1,4 addition by an activated alkene dienophile, maleic acid, across the 9,10 carbon positions of our diene, anthracene. Techniques in this lab include heating the solution on a sand bath in a conical vial that was attached to both the air condenser and then the drying tube, crystallization of the product, and theuse of a Hirsch funnel for filtration.Procedure:The procedure was followed as described in Mayo pages 269-273, with modifications that were posted on Temple University’s Blackboard website in document form under “CHEM 2204, Spring 2016, all sections”. Additional modifications included such of the following:The use of a drying tube was required in which the Drierite (anhydrous calcium sulfate) was substituted with the Drierite (anhydrous calcium chloride).
