Dry THF from still turning wet in seconds

Thats true, both water and oxygen are responsible for the change in color.

The color change is actually due to the presence of oxygen, which quenches the ketyl radicals

@chiralSPO Thats true, both water and oxygen can quench the ketyl racicals. But how would you call the THF when its yellow and only quenched by oxygen ;)

Nah, it was actually a dry day.

Tell me you did this while the rest of the lab was running steam distillations. Wow.
