Anhydrous copper sulfate as AN catalyst?

Copper oxide is used as catalyst in the explosive mixtures with ammonium nitrate but аctually Cu2 + ions catalyze the explosive decomposition of the AN. Copper oxide is preferred because it is anhydrous. Would get if we replace the copper oxide with anhydrous copper sulphate? Will be a cheaper and more practical. Will it work?



Sorry for my english. I am not from England. Thank you!

Copper oxide is easy man, using bicarbonate or carbonate. CuSO4 + Na(H)CO3 -> Na(2)SO4 + CuCO3 +CO2 + (H2O), Then filter and extract the CuCO3, decompose the CuCO3 with a torch, or even just any flame. CuO for days.

Dehydration of copper sulfate is even easier :) Simple heating copper sulphate on stove and from blue turns white.

But you get more bang for your buck (mass) with CuO, since O2- is less than SO42-. Right?

And what are the products from heating CuSO4? You mean you can turn sulphuric acid to oleum that easy?

it would happen to be SO3 and CuO at ~800*C but just above 100*C or some you can observe the CuSO4*5H2O to 'melt' this is actually the H2O going out and evaporating, leaving anhydrous CuSO4
anh. CuSO4 is also really loud if you heat it properly with magnalium or magnesium (:



~25 drops = 1mL @dH2O viscocity - STP
Truth is ever growing - but without context theres barely any such.
