Aspirin Synthesis Introduction Out of all the pharmaceutical drugs in the worlds‚ aspirin is made the most. Any potential pharmacist must be familiar with synthesizing the drug. The goal of this lab is to synthesize as much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H

Synthesis of Aspirin (Acetylsalicylic Acid) Abstract: This experiment is about the synthesis of aspirin under laboratory conditions. Aspirin is prepared by reacting salicylic acid and acetic anhydride; in the presence of sulfuric acid. After fully dissolving the salicylic acid with acetic anhydride‚ the solution is cooled and cold water is then added. Once the crystals form they are then filtered and left to dry out. There mass is measured and recorded then the yield is calculated. Introduction:

unattended. The hot beakers and test tubes must be handled with care and should only be moved using tongs. Also‚ tie back long hair to prevent any accidental fire‚ and be familiar with the location of the fire extinguisher. Discussion The synthesis of aspirin demonstrated here demonstrates several relevant suggestions that should be considered in the synthesis of a substance. Firstly‚ the recrystallization of a product should be performed if possible and relevant. In most reactions‚ the amount of product

preparation of aspirin and oil of wintergreen | Introduction Organic compounds are those which contain carbon as well as a select other elements. An organic acid however‚ is an organic compound which contains acidic properties. An ester is an example of being a derivative of these organic acids. Esters can be prepared by the reaction of carboxylic acids and alcohols‚ with an inorganic acid used as a catalyst which is dubbed esterification. With o-hydrobenzoic acid‚ or salicylic

ANALYSIS OF ASPIRIN: SPECTROPHOTOMETRY The purpose of this experiment is to evaluate the percent aspirin on a commercial aspirin tablet using an instrumental method‚ spectrophotometry. In a spectrophotometer‚ light from a strong lamp passes through a monochromator‚ which breaks the light into its component colors using a grating‚ then uses mirrors and slits to direct a light beam of the desired wavelength through the sample compartment‚ where you place a tube (cuvette) of solution. A detector

Forty million pounds are produced each year. The chemical name for aspirin is Acetylsalicylic acid. Aspirin is a pain reliever and a fever reducer. Aspirin originated from the bark of a White Willow Tree. Chewing the bark however is extremely acidicand irritates the mucous membranes

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
