Why did Fritz Haber develop a process for systhesis of ammonia?
Which are the other production processes of ammonia? (except the ones named below)
One more time I need help. Thank you.
Which are the other production processes of ammonia? (except the ones named below)
Before the start of WWI most ammonia was obtained by the dry distillation of nitrogenous vegetable and animal products; by the reduction of nitrous acid and nitrites with hydrogen; and also by the decomposition of ammonium salts by alkaline hydroxides or by quicklime, the salt most generally used being the chloride (sal-ammoniac) thus
2NH4Cl + 2CaO → CaCl2 + Ca(OH)2 + 2NH3
It can also been obtained by the hydrolysis of many metal nitrides, for example,
Mg3N2 + 6H2O → 3Mg(OH)2 + 2NH3
