t is shown that the stability of amyl nitrite ampuls can be greatly increased by the addition of various substances—including potassium carbonate (solid), trisodium phosphate (solid), magnesium oxide (solid), pyridine (dissolved), and diphenylamine (dissolved). The mechanism of stabilization appears to involve behavior of these agents as sinks for nitrogen dioxide and/or nitric acid produced during the breakdown. The degree of stabilization achieved suggests that the shelf life of the nitrite ester can be readily prolonged as much as tenfold as compared to present commercial products.

The above is a patent from 1958.

Wow! Interesting, thanks for sharing.

BUT do you expect that the major commercial manufacturers are aware of this? If not, I hope they soon discover this and some kind soul informs them.

Yes, NSP; that's from the alkyl nitrite stabilization patent; yes, 1958, back when reactants weren't as pure as they are now, back when 5 to 7 washes were needed.

IF there were even a few molecules of HNO3 in an alkyl nitrite from this century, it would have shown up in the GS/MS spectrographs that I posted yesterday.

there are NONE
