In a lab, we seperated Excedrin (paracetamol, acetylsalicylic acid, caffeine, and binder). First we dissolved the powder in diethyl ether. This seperated the mixture into caffeine/acetylsalicylc acid and binder/paracetamol. K2HPO4 was added to the caffeine/acetylsalicylic acid. Give the reaction mechanism for K2HPO4 + caffeine and K2HPO4 + acetylsalicylic acid. HCl was then added to K2HPO4 + acetylsalicylic acid. Give this reaction mechanism.

Extra-strength Excedrin is a combination of 250 mg acetaminophen 250 mg aspirin, and 65 mg caffeine plus inactive ingredients that are insoluble in water and organic solvents. Using the data in Table E9.1. draw a flowchart to show how these three components could be sepa- rated using their solubility and acid-base properties. Hint: Caffeine is a nitrogen base similar in reactivity to diisobutylamine (Section 7.6.1 and Experiments 2 and 7). HN OH NN OH acetaminophen aspirin caffeine

QUESTIONS 1. In the chromatogram of the analgesic tablet, the peaks for acetylsalicylic acid and caffeine have roughly the same area even though there is 10 to 15 times as much acetylsalicylic acid as caffeine in the tablet. Provide an explanation for this observation. 2. A typical aspirin tablet contains approximately 30 mg of caffeine. How does your answer compare to this value? What are some of the sources of error that could cause a difference between your answer and...

Show structure and cleavage of each step. In a lab, we seperated Excedrir (paracetamol, acetylsalicylic acid, caffeine and binder). First we dissolved the powder in diethyl ether. This seperated the mixture into caffeine/acetylsalicylc acid and binder/paracetamol. K2HPO4 was added to the caffeine/acetylsalicylic acid. K2HPO41+ caffeine was washed with 1) NaCl and then dried with 2) anhydrous sodium sulphate. Give the reaction mechanism for 1) and 2)
