Acetylsalicylic Acid/Aspirin and N-(4-hydroxyphenyl) Ethanimidate/Acetaminophen respectively from Excedrin. The first reaction scheme to undergo acid-base organic extraction was to isolate the most acidic compound in Excedrin with a weak base‚ K2HPO4. We isolated the aspirin using aqueous base extraction‚ with Dipotassium phosphate then treated with HCl to force acidification. The mechanism for Scheme 1 is shown below: The second reaction scheme we used was also an organic acid-base extraction
