Title:
METHOD FOR PRODUCING POROUS GRANULAR AMMONIUM NITRATE
Document Type and Number:
Japanese Patent JP2005350276
Kind Code:
A
Abstract:
To provide a method for producing porous granular ammonium nitrate with a lower bulk density.
The method for producing the porous granular ammonium nitrate with the same hardness as but lower bulk density than those obtained by conventional processes comprises the steps of obtaining an ammonium nitrate particle by drying liquid droplets of an aqueous ammonium nitrate solution, adding an aqueous solution containing a surfactant and a water-soluble organic solvent to the ammonium nitrate particle, and then heating and drying. Preferably, 0.5-5 pts.wt. of an aqueous solution containing 0.5-5 wt.% octadecylamine acetate and 1-10 wt.% ethyl alcohol is added to 100 pts.wt. of the ammonium nitrate particle, and then heating and drying.
