FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. The method of producing ammonium nitrate-sulphate involves preparing solid ammonium sulphate and a mixture containing ammonium nitrate, ammonium sulphate and water, wherein the ratio of ammonium sulphate to ammonium nitrate is less than 0.5. Curing of the product containing an ammonium nitrate-sulphate double salt in ratio of 1:2 from the solid ammonium sulphate and the mixture is carried out while cooling at least part of the mixture at a rate of less than about 100°C/min. The amount of water in the mixture during curing is at least 0.5 wt % per total weight of ammonium nitrate, ammonium sulphate and water in the mixture.
EFFECT: invention enables to obtain a composition which contains ammonium nitrate double salts with low detonation capacity.
