A Greener Synthesis of Acetylsalicylic Acid


Innovating Science™.

Show students it is possible to produce sodium salicylate acid from a naturally-occurring, renewable resource. Students will convert sodium salicylate to salicylic acid, collect and dry prepared salicylic acid. They may then use a quick confirmatory test to examine for the presence of salicylic acid. The prepared salicylic acid can then be used to synthesize acetylsalicylic acid.

There are enough materials for 15 groups. Teacher's manual and student copymasters are included. Materials Included in the Kit: 6 sodium hydroxide 3M, 25mL; 6 hydrochloric acid 3M, 25mL; 1 methyl salicylate, 25mL; 2 acetic anhydride, 25ml; 1 phosphoric acid 85%, 5mL; 1 ferric nitrate, 5ml; 15 pipettes, disposable.
