Has anyone melted their SN in order to drive off O2? I believe the degradation of SN, oxidation to be exact, is what causes spoiled brews in most cases. Degradation to sodium NITRATE makes sweet poppers impossible, reduces good effects, increases side effects, and reduces preservation/shelf life....sometimes less than 12 hours.

I tried melting in a glass skillet. I saw lots of bubbles, presumably O2, coming off. When most of the bubbles disappeared, I quickly poured off into a small crucible, squirted in inert gas, and capped. I have yet to learn if this technique works as I have not had enough time to test my product.

Chemistry literature says to use the metal lead to capture the O2, but is this necessary when already starting with mostly NITRITE?

I think that you only take advance of the melting points sodium nitrate 308 C –sodium nitrite 120 C . So maybe they seperate throw filters ?

I think it's working. Product is much better smelling.....cleaner, nondescript light smelling fluid(NAN) Gets more potent by placing onto fresh Potassium Carbonate and a few MS4.

after reading ,i understand that they seperate them by heating SN up to 275 C (sodium nitrite melts at 271C) . As sodium nitrate melts at 308 C it stays on top ,and they remove it with a spatula

I melted about 14 grams.....in a glass pan about 6 inches in diameter. So I didn't have enough to separate. I saw a lot of bubbles percolating upwards and I assume the bubbles are O2 coming out of the NITRATE.

@Nitritespecialist: the margin between melting points is very narrow; you're not going to be able to melt JUST the nitrite on a stove.

If you got bubbling, you exceeded the melting point of NaNO2, and the whole mess started to decompose (outgassing O2 is a sure sign of decomp).
