The Quench

Not Voodoo Home / Comments? / Anatomy of a reaction

A Perfect Reaction (see all): No quench is necessary

A Nightmare Scenario (see all): The product mixture is highly reactive and requires dropwise addition of quenching reagent to prevent a volcano-like exothermic eruption.

Common Rookie Mistakes: Running Reactions

Step by Step:

  1. Quench at the temperature recommended, at the rate recommended.
  2. If gas is evolved during the quench, or it is otherwise exothermic, watch the reaction carefully to be sure it is under control.
