on water, additionally alkaline solutions absorb carbon dioxide,
converting methoxide into bicarbonate:
CO2 + H2O --> H2CO3
then -OCH3 + H2CO3 ---> HOCH3 + HCO3 -
bicarbonate will not catalyze the reaction
However, if you keep it away from the atmoshpere, it should be stable
indefinitely (storage in glass will degrade slowly)

Thanks for the link, but it still leaves the question of what is the
chemical change that is happening. Does anyone know if it is simply
taking on water?

G'day Andy;
I asked about the same question a whle back and what I got as ananswer was
that once the methoxide is mixed that it can be kept for up to about two
weeks in a cool dark place and sealed.
There is also a formula on the JtF site on how to do a "concentrate" and
then simply add some methanol once you are ready to go.

Subject: [Biofuel] Storage of Sodium Methoxide
Hi,
I have read in many places that sodium methoxide breaks down so it
shouldn't be stored. Therefore you should mix it just before you are
about to use it. Am I correct in assuming that the deacivation is due
to the solution picking up water or is there some other process going
on that I don't know about?
Andy
