R-12 freeon... I read in one thread that it could be substatued for Anhydrouse amonia.. is this true or a load of BS?
Thanks

go ahead and try dissolving Li or Na in freon. might as well try all the other freons too. why would you want to use the "bad" freon when you can get cans of the "good" freon everywhere? i personally prefer maple syrup.

It will probably react extremely violently or explode if you add lithium to freon.

i doubt "explode" would be the right description. for divided K, yes, but solid Li? anyways, Snarg, just a little fun. i was hoping someone would ask "which brand" or "we cant get maple syrup in the EU, is pine oil OK"
freon is used to extract the freebase, nothing more.

It depends.
If you want to use it as a refrigerant, then R12 is pretty good, though I'm not sure it's better than ammonia.... so yes, it could be substituted with this application in mind.
As a precursor to an amine- no. Ie you cannot substitute ammonia with R12 in a chemical reaction which is intended to produce an amine using ammonia as the nitrogen source.
Chlorinated and fluorinated hydrocarbons are fairly unreactive, which is why they find use in refrigeration, and solvents.... and also why they survive for ages, unchanged until they end up all the way at the top of the atmosphere, where they meet hard radiation and ozone and monatomic oxygen and there combine with and deplete - no, can I say "fuck up"? (deplete sounds too ... depleted) the ozone layer.

I don't think a chlorinated hydrocarbon is so stable to reducing agents like an alkali. There is a warning with LAH for example, not to use halogenated fire extinguishers as they can act as an oxidant. Surely the nitrogen is already present in the substance being produced not from the ammonia, I thought the idea was to obtain solvated electrons.

In swims(overly ecologically minded)state he lives in
it would probably be easier to buy lab grade rp from a
company than any of the R's that AC systems are charged with.Tourist on a hot summers day will come in the store and ask to buy one of the $30.00 kits that has 1 can and a hose that you screw on the low side of unit of AC.
Our reply is"they are illegal in *********".Swims state.
The answer is always the same"I bought one before at your
chain in my state.Swim is surrounded by states that sell kits with something other than R-12 or R-134.Its is supposedly ozone safe.
Anyways off the track here.Swim doesn't think he could get R-12.Plus the way the hive's bee's have proved themselves
to be the best chemists time and time again the best can bee had through other means than refridgerant.

If you so dearly want to do some research, try using some higher-boiling amine. Maybee butylamine freebase or something.
It'd surely have a better chance than freon or maple syrup
I've been chased by both cops and robbers. So what does that make me?

This paper by Henne on the reactivity of various haloalkanes with alkali metals should clear up any confusion about this matter, dichlorodifluoromethane doesn't react with alkali metals, and thus couldn't be used in a Birch reduction of pseudoephedrine, unless one wishes to recover the undreduced pseudoephedrine, the alkali metal and the ozone depleting dichlorodifluoromethane as an excercise in futility
