Synthesizing from NH4NO3 is NOT an option

[cbfull]

I thought it would be worth mentioning a couple of things about bench-scale production of N2O.

It seems pretty much all the literature describes the thermal decomposition of NH4NO3. I don't really feel the need to repeat why this is extremely unpredictable, and should never be attempted.

If there were a "chemistry" heading for this substance, I would gladly add a synthesis that is far safer. I admit I'm too tired right now to explain it in full detail, and I'm not even sure it would be appropriate in this thread.

In summary, a mixture of nitric/sulfuric acid is added at a steady rate into a reservoir of urea solution (don't know concentration off hand), and the ensuing reaction is said to generate a steady output of N2O gas that can be increased/decreased by simply changing the rate at which the acid solution is added.

Haven't tried this, don't really plan to, but sounds cool enough.

This Thread already exists considering n2o synthesis, also it is followed by some criticisms.

If SWIY (and please remember to SWIM even when talking about synthesis or topics that are legal where SWIY resides) Has improvements that could be added to that synthesis, an alternate synthesis, or ways of overcoming the problems raised, It might be worth PMing a mod, and they may unlock that thread so you can add to it.

As Snuffkin see's it a synth with some criticism may still be attempted by some, so a better synth with less problems would be an advantage.
