• The precipitation of ammonium perchlorate (AP) from methanol solutions of AP by a salting out method has been studied. The organic solvents studied as precipitants were: chloroform, ether, isobutyl alcohol and methylene chloride. The characteristics of the precipitated AP crystals were investigated by means of scanning electron micrograph, X-ray diffraction, differential scanning calorimetry and thermogravimetric analysis. When ether, chloroform and methylene chloride were the precipitants, the product crystals had a particle size less than 5 μm. On the other hand, the crystals obtained with isobutyl alcohol as the precipitant had a orthorhombic shape and the mean crystal size was larger than 10 μm. Diffraction angles for AP crystals obtained with isobutyl alcohol as the precipitant coincided with those obtained with other precipitants used in this work, though the intensity in the X-ray diffraction changed.
