Development of Process for Producing Fine Particle Size HNS I

摘要

A process was developed for producing fine particle size hexanitrostilbene (HNS) with a mean size of approx. 2 mu m. The process involves dissolving HNS in dimethylformamide (DMF) and slowly adding this solution into a precooled, rapidly-agitated volume of distilled water. The resulting material is then filtered, washed with acetone/water and freeze-dried. The process yield is approx. 98% and provides a material with BET surface area results approaching 10 M exp 2 /g.
