Residue wax coated nitrate salt

摘要

Solvent is extracted by distillation from a residue filtrate generated in producing aluminium paste by filtering a slurry of aluminium particles, at least one fatty acid and a solvent. The distillation produces a residue wax. The wax is used to form a coating composition for coating onto prills of ammonium nitrate to provide at least a part substitute or replacement for conventional fuel oil coatings, especially for use in commercial explosives.
