A Dehydrogenation/Hydrogenation Reaction Purpose: The purpose of this experiment is to determine if it is possible to form aromatic molecules with substances that are not hydrocarbons. We examine ketone monoterpene carvone and treat it with palladium on carbon and heat. Procedure: .135 g of (R)-carvone was treated with 26 mg of 10% Pd/C and heated to 180 degrees C. The reaction was tracked via TLC every fifteen minutes. The resulting product was filtered and diluted with hexane. 10% NaOH was added and the pH was checked. The solution was then acidified by adding 6N HCl, also noting the pH. Diethyl ether was added, and the ether solution was extracted from the stratified solution, dried, measured, and observed. Results: The initial smell of the carvone was minty and slightly floral. The temperature of the system started at 110 degrees C and surpassed 180 degrees a few times. The smell at the end of the heating was less minty and had more of an herbal smell. Once the NaOH is added, light colored layers are produced. The bottom layer, the aqueous, was a
