Does anyone have a printable MSDS for Sodium methoxide solution in methanol?
I am having my first go at biodiesel this weekend and want to be as safe as
possible.
Thanks,

Biofuel] Sodium Methoxide MSDS (Sodium methylate)
Anyway I don't see how an MSDS would be much help to you. This might
be more helpful, from a previous message debunking someone talking
nonsense about methanol:
Methanol is also a very active chemical against which the human
body has

The methoxide that I make by mixing 99% methanol with 85% assay KOH
is volitile and definitely liquid.
You are making a mixture, the volatile component of which is still methanol
So would it be correct to say there's no such thing as methoxide fumes?

This is one of the places where from the fryer to the fuel tank is
wrong/outdated, one more reason to get your information elsewhere!
Could someone here set me straight on my understanding of the
chemistry?
But Ive been told that it's exposure to carbon dioxide that';s the
problem with sodium methoxide going bad, not a time factor instead.
oops, forgot this-
so if that's the case, is this carbon dioxide problem in some way
related to the way the lye 'carbonizes' if left exposed to humid air?

The key to maintaining reactivity with any alkoxide (methoxide,
ethoxide, etc.) is to keep it as dry as possible. Alkoxides are very
strong bases, and in the presence of water, pull a proton off of the
water. this regenerates the alcohol, and produces hydroxide ion.
For example, if sodium
Thanks for the replies to this.
I live in Maine and it is humid here in the summer. I'm wondering if
the reason my last batch of Bio-D didn't work out so well is because
I left it overnight. In a covered bucket, but without a rubber
gasket/seal. Its an old kitty litter bucket that locks down.

Thanks for this, that's very useful.

Sodium methoxide,

It says it's less than 1% NaOH, if I read it right. Quite weak.
Anyway, sodium methoxide is sold ready-mixed. I thought it was, but

Hello Ehren
Good info.
Mike Pelly says in his method that it works better on warm dry days,
definitely true. Humidity is the enemy of biodiesel. Methanol (and
ethanol much more so), sodium hydroxide and sodium methoxide are all
vulnerable to humidity. It's good to know something of the

can anyone tell me the pot life of mixed lye and methanol? assuming I keep
it dry, how long is the mixture stable? Iwould like to mix it up, and
trigger a valve to dump it into the oil vat when the oil reaches
temperature, thus eliminating a lot of hanging around watching oil heat
