Aspirin Synthesis From Salicylic Acid. Aspirin and acetic acid are formed when the hydrogen in Based on the observations, the best solvent was chosen. In the synthesis of aspirin the two reagents are the salicylic acid (c7h6o3) and the ethanoic anhydride (c4h6o3), which is assumed as the alcohol.
Crystallization will be induced by scratching the glass beaker to create nuclei around which aspirin may crystallize. Add 25 drops of ethanoic anhydride followed by one drop of 85% phosphoric acid. The forth test tube is the control.
Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride. This is a substitution reaction where the alcohol group from salicylic acid reacts with ascetic anhydride to form an ester, (acetylsalicylic acid) which is commonly known as aspirin.
The main objective of the synthesis of aspirin lab was so produce aspirin (acetylsalicylic acid) through the reaction of salicylic acid and acetic anhydride. The synthesis of aspirin is classified as an esterification reaction.
Using a clean stirring rod, place a crystal of salicylic acid into the first test tube. Take 1.38 g (0.01 mol) of salicylic acid, 3.06 g of acetic anhydride, one drop of conc.
Place in the water bath and leave for 15 minutes. Aspirin and acetic acid are formed when the hydrogen in
Their solubility was recorded as well. To prepare aspirin, salicylic acid is reacted with an excess of acetic anhydride. Cool down to room temperature and add water (crystallization solvent).!
The synthesis of aspirin is classified as an esterification reaction. Using a clean stirring rod, place a crystal of salicylic acid into the first test tube. To form acetylsalicylic acid (aspirin).
The methods used included recrystallization and scratching to produce a precipitate, which was then filtered to remove any excess moisture. In the synthesis of aspirin the two reagents are the salicylic acid (c7h6o3) and the ethanoic anhydride (c4h6o3), which is assumed as the alcohol. Aspirin and acetic acid are formed when the hydrogen in
Aspirin is prepared by chemical synthesis from salicylic acid, through acetylation with acetic anhydride. A small amount of a strong acid is used as a catalyst which speeds up the reaction. The mixtures were then placed in a beaker of ice water to cool.
Heat for 10 min at 900c.! The reaction equation is shown below: The synthesis of aspirin is known in.
