Abstract
Ammonium nitrate is produced from ammonia and nitric acid, urea being added to the nitric acid and the resulting mixture of nitric acid and complex salt of urea nitrate being neutralized with ammonia. The ammonia may be gaseous or liquid ammonia, or ammonium hydroxide. The amount of urea added is preferably 0.2 to 0.5% by weight of the resultant ammonium nitrate.
