has anyone once EVER tried to see if lithium will dissolve in anhydrous diethylamine? it would be SO SIMPLE to test and it would change EVERYTHING if it work - even if you need a cosolvent like tertbutanol - isn't this worth a TRY?


Osmium

Has DEA suddenly become available OTC for like real cheap or what?


tantric4hrs

how cheap is andydrous ammonia? and EDTA IS dirt cheap and every where. besides, EDA is safe and easy to work with, pure NH3 is corrosive, deadly and utterly watched - i'm just saying, wouldn't it be worth a try?

and DEA diethylamine, is not the same as EDA, ethylenediamine - besides the instant panic the initials DEA cause....

and yes, i screwed up in the original post and called it diethylamine - i meant ethylenediamine, sorry


Osmium

> how cheap is andydrous ammonia?

Very cheap.

> EDTA IS dirt cheap and every where. besides, EDA is safe and easy to work with,

EDTA is not EDA. And DEA is yet another chemical.

> pure NH3 is corrosive,

Just like the other amines.

> deadly

Not much more deadly than the other amines.

> and utterly watched

Not nearly as watched as DEA.

It doesn't work the way that you think, read these for the reason why  ;)

anhydrous ammonia is cheap - but very well guarded. and what does DEA have to do with anything? EDTA is ethylenediamine tetracidic acid - can this not be reacted with a base to make EDA? the "metal ammonia solutions" book very clearly states that lithium will dissolve in an diamine. sorry, though, i'm on dial up and it will take me a while to read over those refs.

This article goes on to state:

Lithium - doesn't dissolve in dimethylamine but is quite soluble in ethylamine

and BTW, i did read the ENTIRE metal-ammonia solution book

ps - i'm having not luck what so ever trying to read those refs what format are they in? i mean, i can download them, but them my computer has NO idea how to deal with them

No. EDTA is NOT the salt of one molecule of ethylenediamine and 4 molecules of acetic acid! You cannot remove the acetic acid part with base, since it isn't a salt.

> and what does DEA have to do with anything?

Well, you mentioned it in the thread title: "lithium and diethylamine"!
Ethylenediamine and diethylamine are two different compounds.
