Hydrolysis under acidic conditions
Taking ethanamide as a typical amide:
If ethanamide is heated with a dilute acid (such as dilute hydrochloric acid), ethanoic acid is formed together with ammonium ions. So, if you were using hydrochloric acid, the final solution would contain ammonium chloride and ethanoic acid.
So urea would yield cyanuric acid and NH4Cl as a byproduct?
anyway that reactions useless and doesn't achieve the goal.
basic hydrolysis will form sodium cyanate.
ning said acid hydrolysis was the way to go, remember?
Maybe he didn't know ammonium carbonate/bicarb/carbamate was wanted.
Theres the hexamine MeAm synthesis, but urea would have been nicer for a NH4Cl source because it would'nt be contaminated with a controlled substance before it's ready for use...
I suppose HCl + household ammonia isn't so bad. :)
Hydrolysis under alkaline conditions
Again, taking ethanamide as a typical amide:
If ethanamide is heated with sodium hydroxide solution, ammonia gas is given off and you are left with a solution containing sodium ethanoate.

and also
Well there's nothing I don't like about Hcl and ammonia water, but I was just looking at different ways.
Plus it sounds like the urea reaction you detailed would involve less water to evaporate, which is good! :)
Do you know how long the reaction would take, temperature, and also whether a lower concentration of HCl can be used?
