The reagent is HNIW (hexanitrohexaazaisowurtzitane) which is used as weapon and propellant such as explosives. In study, firstly solubility was researched because that is the first step in the crystallization process and then the phenomenon that forms of HNIW were changed was founded. Results of solubility have been used as reference for solvent and anti solvent. Finally, ACT, EA, DMSO, BL and ACN are solvents and 1-propanol, 2-propanol which is we called IPA are anti solvents. Also, the form of HNIW was affected by supersaturation. ACT was chosen as solvent due to the highest solubility. Anti solvent was used as IPA because when IPA led to make the smaller size than when we used the 1-propanol. Also, precondition is that low supersaturation since ɛ form was found in lower supersaturation than supersaturation where β form appeared. |
