Question

Grignard reactions are highly exothermic and are performed in ether solvent. There is a real risk of fire during this reaction. In the case that a fire should occur in your distillation apparatus, what is the best course of action?

Answer 1

Ideally, extinguish the flames with a glass watch or beaker.

Step-by-step explanation:

When you cover the distillation equipment with a watch glass or beaker, you reduce the oxygen content and it is completely eliminated thanks to the fire itself that consumes it. Once there is no more oxygen the fire is extinguished and it should take no more than 2 or 3 seconds to occur this situation

It is the easiest and most careful way to extinguish the fire during the Grignard reaction
