1_rxn_run.mp4Add a small stir bar to the RBF
Attach a microscale condenser using a small amount of grease and Keck clip
Place the apparatus half-way in the boiling water bath and let the system react for ~5 minutes
Step 4. Quench excess acetic anhydride and allow to react for another 5 min.
Step 4. Quench excess acetic anhydride and allow to react for another 5 min.
quench.mp4Carefully move the apparatus out of the water bath and allow the system to cool to room temperature
Add 1 mL of water through the top of the condenser to quench excess acetic anhydride
Place the system back in the water bath and allow this to react for an additional 5 minutes
Discuss: In-Lab #2
