potassium nitrousamine

"I accidentally made Potassium nitrousamine (which is really carcenogenic), and then inhaled a great lungfull of it..." - Ramiel

How do you make this? I think it would be good if people knew how (not) to make it since it can be accidentally made so easily.

It's spelled 'nitrosamine'.

A Google search reveals that it is commonly encountered via an incubated environment, from nitrites and gastric juices. I certainly didn’t spew in the reaction (although I may have later :( )

It was just Potassium nitrite and Al/Al<sub>2</sub>O<sub>3</sub> at temperatures of around 60-80 deg. C (I can’t remember). As <html><u>do</u></html> remember, I was evaporating the water in a nitrite solution.

I suspect the Aluminum catalyzed the reaction somehow, I don’t know exactly how that would work though (primarily why I didn’t anticipate such a calamity).

Perhaps more 3l3te chemists can shed some light on this little matter.

Potasssium nitrosamine?

Is that the same as potassium hyponitrite, K2N2O2?
2 K (+) O-N=N-O (2-)
Which is formed by reducing nitrites with Al/Hg,
Or do you think you produced a bit of ammonia (which is done by reducing nitrates/nitrites in alkaline conditions with metals - Al, Zn etc), and then this reacted further with nitrite ions to produce the potassium salt of nitrosamine, K (+) H-N-N=O (-)

I remember that I once tried to produce hydrazine by reducing NaNO2 with Al, I don't remember exactly what I did but I came back to the reaction a little while later to find that it'd thrown caustic solution all over the place, with a strong ammonia smell.
