    How do you make aspirin from salicylic acid?
    Place 5.0 g of salicylic acid in a 100 mL Erlenmeyer flask. followed by 1 mL of concentrated sulfuric acid. Stir the mixture gently observing the rise in temperature to 70-80 °C while the salicylic acid dissolves. for 10 minutes after that solid mass of aspirin will be formed. Air-dry the products, weigh, and calculate the yield.

    What is acetylsalicylic acid (aspirin)?
    It uses a reaction of esterification catalyzed acid (H 2 SO 4 or H 3 PO 4 ), where the salicylic acid treated with acetic anhydride gives acetylsalicylic acid (aspirin). In this reaction, it becomes a hydroxyl group to an ester, obtained as a by-product acetic acid. It is a drug that is found in the list of essential medicines of the WHO.

    How is crude aspirin purified?
    In this purification method, the crude aspirin will be dissolved in a small amount of warm ethanol. Water will then be added and the solution will be cooled slowly and then chilled. The acetylsalicylic acid will recrystallize, and the solid impurities (unreacted salicylic acid) should remain dissolved in the solution.

    How do you make acetic acid from aspirin?
    (These tubes of cold water will be used to rinse the solid aspirin after you collect it on the filter paper.) After the reaction has gone on for 15 minutes at 100°C, add 1 mL of deionized water to the flask. This water will react with any excess acetic anhydride, converting it to acetic acid. Remove the flask from the water bath.

    How do you make aspirin crystallize?
    Use cau-tion: the hydrolysis may cause spattering. Add 15 mL of water and cool the 100 mL beaker in a larger beaker with ice water. Stir with a stirring rod. Allow 5 minutes for the aspirin to crystallize from the solution. In the meantime, put a wash bottle filled with distilled water in ice water to cool.

    How do you know if salicylic acid is present in aspirin?
    However, if salicylic acid is present you will see a violet color develop; the amount of violet is directly related to the amount of salicylic acid present in your aspirin. Obtain approximately 2 g of salicylic acid and de-termine its mass accurately; record the exact value in your data table. Transfer to a 100 mL beaker. Do this step in the hood .
