What is the more formal chemical name for aspirin? Acetylsalicylic acid 2. Using your data from Experiment 2‚ how can you be sure you synthesized aspirin? By using the colors as a guide‚ we can compare the Acetylsalicylic acid + 8 mL FeCl3 to the Aspirin Crystals from Experiment 1 + 8 mL FeCl3 in order to see if it synthesized. 3. Would you say that your synthesized aspirin is relatively pure? How can you tell? One way that the purity of aspirin can be judged is by it’s color as pure acetylsalicylic

Abstract By separating chemicals out of a mixture and purifying them through sublimation and recrystiliation‚ changes in the substances physical properties can be shown. A salicylic acid-naphthalene mixture was mixed together with diethyl ether and saturated sodium bicarbonate. Two layers separated and were extracted after acidifying with HCl. This precipitated the crude salicylic acid. The left over mixture was combined with water and the two layers separated where crude naphthalene was recovered

Experiment 22: Synthesis of Aspirin and Oil of Wintergreen Performed 01/31/2013 Received 02/07/2013 Organic molecules have a wide range of applications occur both intracellular as well as in many different industries. The reactions use the reactivity of functional groups attached to organic molecules‚ as well as general chemistry concepts such as Le Chatelier’s Principle (). The synthesis of Aspirin (its chemical name being acetylsalicylic acid) and of oil of wintergreen (with its chemical

As we know‚ the TLC is a separation technique that has two phases: the stationary phase and mobile phase. The stationary phase is silica gel (SiO2) which is very polar compound‚ while the mobile phase is 0.5% acetic acid which has less polar. Also‚ as we know‚ the compound will rather to stay with stationary phase or travel with mobile phase depend on its polarity. The result show as that the polarity of the solvent is the key factor for the compound to travel with it or stay in stationary phase
