METHOD OF PRODUCING GRANULAR AMMONIUM NITRATE Russian patent published in 2014 - IPC C05C1/00 

FIELD: chemistry.

SUBSTANCE: method of producing granular ammonium nitrate involves adding a stabilising additive to an obtained ammonium nitrate solution while simultaneously neutralising the obtained solution with ammonia, evaporating the obtained solution until a melt forms, granulating the melt, wherein to increase absorption capacity of granular ammonium nitrate, granules are treated with a stabilising emulsion, the continuous phase of which is diesel fuel and the dispersed phase is water, with a variable ratio of the water phase to the oil phase of 1:(1.5-9).

EFFECT: invention enables to obtain granular ammonium nitrate with high static strength, low caking capacity and residual moisture content, high absorption and retention capacity without using blowing agents.
