Procedure: Measure and dispense 0.6 ml of a 4.4 M solution of sodium methoxide in methanol and of ethanol into a 5 mL reaction vial. Add 2.5 mmol of acetaminophen (-0.378. Set up for reflux in the rume hood and bring reaction to reflux for 15 minutes (solvent is boiling and vapors are condensing on condenser). After 15 minutes directly through the top of the condenser tube, carefully...

Question to answer from the lab: What aspect(s) of the approach taken is/are NOT especially green? What changes might be made to make the overall process greener? The Lab Experiment Summary Polyethylene glycols such as PEG-400 are currently of great interest to organic chemists, since their application as reaction solvents is very intriguing (1). PEG-400 is non-volatile and nonflammable in nature, and also possesses important properties such as recyclability, ease of work-up, thermal stability and economical cost. In addition, the...
