Using Sodium ethoxide to improve azide yeild

XeonTheMGPony - 21-6-2019 at 04:37

Hypothesis:

I am contemplating using some Sodium Ethoxide to compensate for the moisture content in the Sodium Hydroxide

I can not see any overt side reactions this could cause.

No matter how well I dry the Alcohol and the glass wear the sodium hydroxide is a much more difficult prospect, so instead of drying it consume burn it off with Ethoxide.

Or am I out to lunch and missing some thing massive?

Proposed procedure:

Oven dry glass wear at 150c for 1 hour
Get purified Ethanol that has been distilled over sodium hydroxide and further dried over molecular sieve.
Sodium Hydroxide.

Assemble glass wear and drying tube (Thistle type with Calcium Chloride)

Add 100ml anhydrous ethanol, add 1 grams sodium metal
18.6g Sodium Hydroxide (at about assumed 5% moisture it will be about 0.93g of water)

While that all is dissolving / reacting:
Do hydrazine extraction with will resualt in 100Ml of the anhydrous ethanol / Hydrazine

Run reaction as per usual.

Any thing wrong with this proposed method?

I would try to get dry NaOH, the stuff I get is dry, at least not more than 0,5% water. And it is just drain cleaner from the hardware store.

I can't comment on your proposed procedure because you don't give the full procedure, I don't know the "usual".
