  • A standard Soxhlet extraction apparatus was found to maintain a temperature of 49°C in the extraction chamber when cycling benzene distillate through a thimble filled with molecular sieves
  • Slanting the condenser away from the reaction pot also alleviates potential contamination of the reaction that can result due to external condensation of atmospheric humidity, followed by penetration of the ground glass joint
  • Other glassware has been designed for the purpose of conducting reactions at high dilution that also uses slow addition of reagents through dilution by distillate return

  • For larger scale reactions, the bulk of the H2O can be distilled and removed first, and then molecular sieves can be used to scavenge the remaining H2O
  • Although C could potentially become blocked by the drying agent, this problem has not been encountered, and could be overcome easily by protecting the entrance to C with glass wool
