Does anyone know what this is chemically please ?
I notice that the fuel pod 2 uses it as a recommended alternatine to methoxide

On the "Safety" page, under "Chemicals" they mention " Sodium methylate",
which is another name for " Sodium methoxide".

Quite why they make this non-distinction is beyond me.

The data reads more like that of engineers than chemists, so perhaps the "Chemical info" is bought-in,
while they concentrate their skills on manufacturing?

I have since discovered that the difference is that sodium methylate is anhydrous wheras dissolving hydroxide in methanol releases 18 g water for each 40g hydroxide dissolved.

Interesting.So presumably that means lower soap production and higher conversion efficiency?

Lower soap would be good.
When i get the time i wil try a coulple of small test batches.
A with methoxide
B try drying the methoxide with molecular sieve first.

Maybe a dessicant would work? A lot cheaper than molecular sieves, and I'm not sure a molecular sieve will separate out water and methoxide - usually they're used for separating out heavy organic molecules (proteins, long chains etc) from light inorganic molecules.

like petrol is used to break the celulose chains and release the cocane?

Can't tell you Amy - I've never processed cocaine.

I used to use molecular sieves daily for about 8years, to separate antibodies from lysine-sequestered luminescent tracer, though. They're not very exciting, require constant whetting or they crack and the stuff runs through the cracks and you have to start all over again.

lysine luminescent sounds like the colour seen in cooked rice when its been left in the fridge too long, (not my fridge, i hasten to add) and its deadly poisonous.
