Was this helpful?People also askIs aspirin an organic ester?Is aspirin an organic ester?Aspirin is an organic ester. An ester is a compound that is formed when an acid reacts with an alcohol, -OH group. Acetic anhydride reacts with Salicylic acid to yield the ester (aspirin).Preparation of Aspirin Lab Report - AcademicscopeSee all results for this questionWhat is the preparation of aspirin?What is the preparation of aspirin?For preparation of Aspirin, acetic anhydride is added to the measured amount of salicylic acid. Sulphuric acid is added and heated for a short period to complete reaction. Water is added once removed from heat with addition of cold water and suction filtration is carried out.Synthesis of Aspirin Lab Report - AcademicscopeSee all results for this questionWhat is the percent purity of aspirin?What is the percent purity of aspirin?Use your percent purity calculations to determine the percent yield of your synthesis of aspirin. The objective of this experiment is to enable us to conduct the synthesis of aspirin, reinforce the skills of recrystallisation and reinforce the technique of melting point determination. It is carried out to form ester from an acid and an alcohol.Synthesis of Aspirin Lab Report - AcademicscopeSee all results for this questionHow do you test the purity of aspirin?How do you test the purity of aspirin?One way in which you could test the purity of the aspirin in this experiment would be via testing its melting point against pure aspirin made. Another way would be to test it via the reaction of ferric chloride. Ferric chloride tests for the presence of phenols. Aspirin is a phenol.Preparation of Aspirin Lab Report - AcademicscopeSee all results for this questionFeedback

It is also useful in organic chemistry for the test of alcohols and carboxylic acid. It is used in polymer industry. Esterification reaction is used in the manufacture of paints, varnishes, lacquers, medicines, dyes, soaps and synthetic rubber. Results: Mass. Mass of salicylic acid = 7. Mass of dried, recrystallized aspirin = 10. Percent yield3.6/5(39)

SYNTHESIS OF ASPIRIN (acetylsalicylic acid) Place 2.0 g (0 mole) of salicylic acid in a 125-mL Erlenmeyer flask. Add 5 mL (0 mole) of acetic anhydride, followed by 5 drops of conc. H 2 SO 4 ( use a dropper, H 2 SO 4 is highly corrosive ) and swirl the flask gently until the salicylic acid dissolves.

Synthesis of Aspirin Lab Report. Abstract: The goal of this experiment was to synthesize aspirin. In this experiment aspirin, also known as acetylsalicylic acid, was synthesized from salicylic acid and acetic anhydride. In the reaction the hydroxyl group on the benzene ring in salicylic acid reacted with acetic anhydride to form an ester functional group.[PDF]
Experiment 5 - Synthesis of Aspirin
aspirin product as well as a commercial aspirin tablet will be compared to a standard 0% ferric-salicylate solution. In the presence of moisture, aspirin may decompose (hydrolysis) into salicylic acid and acetic acid. This reaction is the reverse of the synthesis reaction. The maximum allowable amount of
