Brittney Brown November 12, 2009 Vanillidenacetone Questions 1. Vanillidenacetone from vanillin 2. The aldol reactions are important to synthetic organic chemist because it can combine two simple molecules into a more complex compound. Adol reactions are part of the production of commodity chemicals such as pentaerythritol and in the pharmaceutical industry in the synthesis of optically pure drugs ( 2 ). 3. The Clasien-schmidt reaction results from the addition of sodium hydroxide to the mixture of acetone and vanillin ( 1 ). 4. Table 1. IR peaks and their corresponding functional group for cyclohexanone Location of Peak (cm -1 ) Functional Group 3229.00 O-H (Alcohol) 1516.62
