| 제목 | Solubilty of β-HNIW in binary solvent mixtures |
| 초록 | The nitramine 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hex-aszaisowortzitane (HNIW or CL-20), is the most powerful commercially available explosive at present. HNIW has four polymorphs, oh which usually existed as ε-HNIW and β-HNIW in organic solvent. Polymorph transformation is affected by supersaturation, temperature, solvent composition. Therefore solubility of β-HNIW in binary solvent mixtures should be measured in order to determine effect of supersaturation on polymorph transformation. Solubility of β-HNIW in binary solvent mixtures (ethyl acetate + n-heptane, ethyl acetate + 1,1,2-trichloroethane) at temperature range between 283.15 and 333.15K was measured by gravimetric method. β-HNIW in binary solvent mixtures is metastable form. So solubility was quickly measured before occur transformation. Solubility of β-HNIW in binary solvent mixtures was decreasing with increasing temperature and mole fraction of n-heptane, 1,1,2-trichloroethane |
