FIELD: chemistry.

SUBSTANCE: invention can be used in chemical industry and in production of explosives. The method of producing water-resistant ammonium nitrate includes simultaneously grinding and mixing ammonium nitrate with a mixture of water repellents containing iron (III) oxide in amount of not less than 0.03% and stearates in amount of not less than 0.1% of the weight of the product, and drying. The stearate contained in the water repellent is lithium stearate or magnesium stearate or a mixture thereof. The water repellent additionally contains oleates of group IIA metals or mixtures thereof, taken in amount of 0.1-1.0% of the weight of the product, with the ratio of stearates to oleates of group IIA metals of 1:1.

EFFECT: invention enables to obtain ammonium nitrate with high water-resistance.
