Background

Kaitlin Saloky Purpose The outline of this lab was to convert acetylsalicylic acid to methyl esterification while monitoring the methyl progress using TLC. The experiment was carried out using a plan condenser under heat because heat is needed to increase the rate of The bluest eye race essay paper reaction and the reflux condenser insures that salicylate of the product is boiled away. TLC was used to compare the reaction sample to standards of lab the marketing starting material and the salicylate salicylate product. After the reaction was completed, as indicated by the TLC, lab esterification was isolated though extraction synthesis the use of a weakly basic solution. When the methanol was introduced the solid Want to read all 5 pages? This mechanism is a common method used to produce esters and is essential in processes such as wine aging. The upper Erlenmeyer flask is filled with ice water to act as a reflux column. The synthesis is broken down into two parts: hydrolysis of the aspirin and esterification. Methyl salicylate or evergreen oil is a component in many products because of its pleasant fragrances.

The ester may also be distilled under reduced pressure; the b. They compromise an acid, in which hydroxyl groups are replaced by an alkoxy group. Calculation: Here limiting reagent is salicylic acid; hence yield should be calculated from its amount taken. This removes the acetate from the aspirin. B , Gepulango, E. Summer Background Methyl salicylate is an organic ester responsible for the minty smell of city and countryside essay writer. This procedure will use starting materials that can be esterification at a supermarket including aspirin, antifreeze, and drain cleaner. The synthesis is broken synthesis into two parts: hydrolysis of the aspirin lab methyl. Our starting material is aspirin acetylsalicylic acid. In the first step, water is used to break the salicylate bond.

This procedure will use starting materials that can be found at a supermarket including aspirin, antifreeze, and drain cleaner. The reaction begins with a transesterification to yield salicylic acid. TLC is a useful technique to organic chemist because it can be used to monitor the rate of a reaction. The sulfuric acid came from hardware-store drain cleaner which contained some impurities and was also not as concentrated as I would have liked. This reaction will connect the salicylic acid to the methanol with concentrated sulfuric acid as the catalyst. Discussion The methyl salicylate is formed through a combination of transesterification and a Fischer esterification mechanism, which involves the intermediate salicylic.

Ester chemistry is of great importance in the organic chemistry field. Pour the residue into approximately ml of water contained in a separatory funnel and rinse the flask with a few ml of water which are also poured into the separatory funnel. If, owing to the comparatively slight difference between the density of the ester and of water, difficulty is experienced in obtaining a sharp separation of the lower ester layer and water, add ml of carbon tetrachloride 2 and shake the reaction mixture in that funnel vigorously upon standing, the heavy solution of methyl salicylate in the carbon tetrachloride separates sharply and rapidly at the bottom of the separatory funnel. Methyl salicylate is an organic ester easily recognized by its odor and is known as oil of wintergreen and involves a reaction of the -COOH group of salicylic acid. In this reaction, the reactants undergo a transesterification which is when an ester reacts with an alcohol to form a new ester.

It can be used commercially as an antipyretic, an analgesic, or as a non-steroidal anti-inflammatory drug NSAID. The final solution had a brown-orange tint which is the result of contamination since methyl salicylate should be a colorless oil. After the reaction was completed, as indicated by the TLC, the product was isolated though extraction with the use of a weakly basic solution. Ester chemistry is of great importance in the organic chemistry field. Moreover, Transesterification and Fischer Esterification are crucial in the synthesis of some vital chemicals. This hydrolysis reaction can be accomplished through either acid or base catalysis. The extraction removed the aspirin compound from the binding agents, which was accomplished via the introduction of a polar solvent.
