Last updated: 7/27/2022

The aspirin substitute, acetaminophen (C8H₂O₂N), is produced by the following three-step synthesis: i. C6H5O3N(s) + 3H₂(g) + HCl(aq) → CeHs ONCI(s) + 2H₂O(l) ii. C, H, ONCI(s) + NaOH(aq) → C6H7 ON (s) + H₂O(l) + NaCl(aq) iii. C&H7 ON (s) + C₂H6O3(1)→ Cg H₂O₂N(s) + HC₂H30₂ (l) The first two reactions have percent yields of 86% and 94% by mass, respectively. The overall reaction yields 13 moles of acetaminophen product for every 17 moles of C6H5O3N reacted. a. What is the percent yield by mass for the overall process? b. What is the percent yield by mass of Step III?
