Claims (12)
1. A process for the preparation of ammonium nitrate which comprises reacting ammonia in the gas phase with an excess of an oxidizing agent providing molecular oxygen under the reaction conditions at a temperature sufficient to cause the formation of nitrogen oxide reaction products, and reacting said reaction products with about a stoichiometric amount of ammonia gas at a temperature in the range of from about 60°F. to about 425 °F. to form ammonium nitrate.
2. The process in claim 1 in which the oxidizing agent is molecular oxygen.
3. The process of claim 2 wherein the molecular oxygen is present in an amount of at least about 3. 6 parts, by weight, per part ammonia.
4. The process of claim 2 wherein the molecular oxygen is present in an amount of at least about 5. 0 parts, by weight, per part ammonia.
5. The process of claim 1 wherein the reaction of ammonia and the oxidizing agent is carried out in the presence of a catalyst.
6. The process of claim 5 wherein the reaction of ammonia and the oxidizing agent is carried out by passing through a platinum wire gauze catalyst.
7. The process of claim 1 wherein the temperature of the reaction between said reaction product gas and the ammonia is maintained in the range from about 90°F. to about 200eF.
8. • " 8. The process of claim 1 wherein the temperature in the reaction of ammonia and said reaction product gas is maintained at a level such that the ammonium nitrate formed is in the solid state.
9. The process of claim 1 wherein the temperature in the reaction of ammonia and said reaction product gas is maintained at a level such that the ammonium nitrate formed is in the molten state.
10. The process of claim 1 wherein the temperature in the reaction of ammonia and said reaction product gas is maintained at a level such that the ammonium nitrate formed is in an aqueous solution.
11. A process for the preparation of ammonium nitrate, substantially as hereinbefore described with reference to the accompanying drawings and to the Examples.
12. Ammonium nitrate whenever produced by the process according to any of Claims 1 to 11. For the Applicants Dr. Yitzhak Hess
