Lab : Aldol Condensation Purpose. In this lab you will conduct the Aldol condensation reaction under solid-state reaction conditions that will involve grinding reactants in the solid phase. You must read ahead and learn about this reaction and the chemical mechanism for the Aldol condensation. There are two possible products which are the initial Aldol or subsequent elimination product. You will need to isolate and purify your reaction product. You will use your melting point, IR, 1H and 13C NMR spectra to...

Process A. Preparation of 4-t-butylcyclohexene Assembling the equipment Fill the almost complete sand bath, place it on the base of the shelf, fix the thermometer with a clip and start heating until the temperature of the sand is - 110C. B. Mixing the reagents Using the plastic funnel, introduce 0.60-0.70 g of 4-t-butylcyclohexanol into a large, clean, dry test tube. Then add 10 drops of concentrated phosphoric acid, 3 drops of concentrated sulfuric acid and a pebble to moderate boiling....

PROCEDURE CAUTION!!! Nitric acid and sulfuric acid are strong and corrosive acids. For that reason, avoid inhaling its vapors or causing any contact with the skin or clothing. Wear your protective glasses at all times. Use the extractors to work with these acids. A. Nitration of methyl benzoate 1. Preparation of the reactants. In the extractor you will find a burette with concentrated sulfuric acid, a second burette with concentrated nitric acid, clearly identified. Familiarize yourself with the scales of...

Page 1 Synthesis using Carbonyl O-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the organic starting material (what you have to work backwards toward) depends...
