Breaking fluorine-carbon bonds

symboom - 10-12-2019 at 12:13

Watched a video on how lithium can break sulfur hexafluoride
Into lithium sulfide and lithium fluoride

And I know fluorine carbon interaction is the strongest known bond but can lithium break up 1,1-difluoroethane used as canned air and R134a refrigerant for cars

never heard of magnesium/teflon thermite?

I did not think it merited its own thread but as long as this one exists i would love to know some milder methods to replace the Fluorine-Carbon bond with a Oxygen-Carbon one for an idea i have been trying to refine.

The ones i know of now is alkali hydroxides and ballmilling with Calcium Oxide
Alkali oxides should work too right?

I suspect that a mixture of steam and R134a passed over something like CaO at red heat would react to give CaF2 and a mess of volatile organics.

However, one reaction you can definitely get from R134a and hot air is the production of HF and or COF2 (the fluoro analogue of phosgene).
So be very careful.

symboom, link the video!

That's one of the two uses for SF6 I know of (the other being an insulating gas for power boxes). I read about it as a propulsion method for torpedoes - the Stored Chemical Energy Propulsion System (SCEPS).

It is the chemical force channel

Sounds like a recipe for death
