Abstract
A novel method of producing metal chlorates is described which involves the reaction of ammonium chlorate with metal carbonates and/or metal bicarbonates. The reaction yields extremely pure metal chlorate, as well as ammonia and carbon dioxide by-products. These by-products combine to produce ammonium bicarbonate. The ammonium bicarbonate may then be reacted with sodium chlorate to produce ammonium chlorate, which may be recycled for use in the production of metal chlorates.
Claims19
A method of producing chlorate salts comprising:
- reacting a compound selected from the group consisting of a metal carbonate, a metal bicarbonate, and mixtures thereof with ammonium chlorate to produce a metal chlorate and reaction by-products;
- wherein the metal in the metal carbonate or the metal bicarbonate is a Group I metal.
