Hi Science Madness community, nice to meet you. I have been a reader here for several years now, and am only now joining. I hope to be able to ask
good questions that yield answers to help other readers and to jog the minds of the knowledgeable. I may be able to share experience on some matters, but am generally here to learn. I thank you for your time and
eyes!
So then the question of this post is:
Are tetraalkylammonium hydroxides hard to make or aquire/request?
Such as TBAOH?
And, what uses would a chemist have for TBAOH, instead of say potash flakes (KOH) or NaOH?

Solutions of TBAOH are comercially available.
TBAOH can be made from TBAChal and Ag2O (+ H donor), possibly also from TBAHSO4 and Ba(OH)2.
Try this:
Take nitrobenzene and add to it small amount of solid NaOH.
If nitrobenzene is pure - nothing happens (at room temp).
Next, add small amount of TBACl (or similar).
Immediately deep red colour of Meisenheimer complex appears.
TBAOH is very strong and soluble base, it attacks even such inert reagent like mononitrobenzene.smuv - 27-2-2011 at 12:33
TBAOH can also be prepared from the chloride via NaOH in alcohol. The sodium chloride precipitates.
