heating ammonium nitrate in a mostly sealed container to temps in the 700-1000°C range isn't going to cause anything dramatic to happen with the
nitrate.. |
My experience with C.A.N was that the filtered crystals were cream-coloured, so I heated the filtrate above its MP (170°C) in a casserole dish until
decomposition had just begun, about 210°C.
When the bubbling liquid solidified, it was snow-white as the gas-liquor contaminents it had contained had been oxidised.
Recrystalising then gave long, clean crystals...
For producing NA, though, it's more convenient (and efficient) to react boiling sols of AN and KCl and distill the acid from the KNO3
formed, using H2SO4.
