Title: lithium and diethylamine
Post by: tantric4hrs on December 15, 2003, 06:17:00 AM
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?

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

Title: well, no but...
Post by: tantric4hrs on December 16, 2003, 05:07:00 AM
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

Very cheap.

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.

Title: just a bit more
Post by: tantric4hrs on December 16, 2003, 06:46:00 AM
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.

(only on proplonged cooling to 193 K)
( slightly at room temp; moderate on cooling to 193 K)
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.
