Conditions for the Reaction to Occur/ Type of Reaction

WHAT ARE THE CONDITIONS UNDER WHICH AMMONIUM NITRATE IS CREATED AND WHAT IS THE TYPE OF REACTION?

The processes involved in the production of ammonium nitrate in industry, although chemically simple, are technologically challenging. The acid-base reaction of ammonia with nitric acid gives a solution of ammonium nitrate.This is done using anhydrous ammonia gas and concentrated nitric acid. The reaction that occurs is called synthesis (which is when two or more simple compounds combine to form a more complicated one) and is very violent. After the solution is formed, the excess water is evaporated to an ammonium nitrate (AN) content. The AN melt is then made into “prills” or small beads in a spray tower. It can also be made into granules by spraying and tumbling in a rotating drum. The prills or granules are then dried, cooled, and coated which prevents caking. These prills or granules are the typical AN products used in commerce.
