How would do this synthesis ?

Triethylamine or TEA is easy to purchase, more than triethanolamine. At least in Latin America. I think this synthesis is unprofitable.
But only in theoretical mode, you can transform the (OH) group of the amine in halogen groups and then discard the halogen groups to obtain TEA.
The first step is halogenate the (OH) groups with triphenylphosphine and TCCA, see here: http://www.sciencemadness.org/talk/files.php?pid=569493&... and later exclude this halogenated groups with Zn, ammonium chloride and THF, to
obtain TEA, see here: http://www.sciencemadness.org/talk/files.php?pid=515465&...

I suspect that the first step gets you dangerously close to chemical weapon precursors.

You're right @unionised. Tris(2-chloroethyl)amine is also knowed as Nitrogen Mustard and is extremely toxic like other blister agents. I did not even
realize this. But, of course, I was talking about theoretical chemistry. You'd better purchase TEA directly from a supplier.

I didn't even know about the weapons. Thus I won't try this synthesis, so I'll need to buy triethylamine. Now, as a question: this means that
triethanolamine is a suspected chemical? I mean, is it awkward to buy it ?

Does Hydroiodic acid and red p work on nonbenzylic amino alcohols or not? ie ethanolamin to ethyl amine?
