G’day Martin; DIRE WARNING!!! Mixing concentrated nitric acid with
alcohols (ethanol; methanol) is very dangerous, even in the cold.
There is usually a very violent reaction after a few seconds, when I
have seen the contents of the vessel shoot all over the place. In
fact, I have seen quite a few laboratory ceilings painted with this
material. Especially undergraduate labs. Not at all a good idea!
Nitric acid is a very powerful and vigorous oxidising agent, and the
alcohols are good reducing agents. Pouf Boume!!! As the French say.
Cheers for now,
