中文摘要：

采用高压相平衡法和紫外分光光度法测定了308.15～328.15K和8～23 MPa时废旧B炸药组分在超临界二氧化碳流体中的溶解度.结果表明,石蜡溶解度随温度和压力的升高而增大,最大溶解度为1.3922 g/gco2.TNT和RDX溶解度曲线存在一个转变压力pven,当压力小于pvert时,溶解度随温度增加而降低,当压力大于pvert 时,溶解度随温度的升高而增大.TNT的最大溶解度为7.42×10-3g/gco2,RDX的最大溶解度为8.035×10-5g/gco2.基于实验结果,提出了超临界技术分离废旧B炸药的工艺.

英文摘要：

The solubility of three components of wasted composition B in supercritical carbon dioxide was measured by high phase equilibrium and UV spectrophotometry at temperature of 308.15-328.15K and pressure of 8-23 MPa.The results show that the solubility of wax rises as the temperature and pressure increase,and its highest solubility is 1.3922 g/gco2.The solubilities of TNT and RDX change regularly with a convert pressure（pvert）.When the pressure is less than p the solubilities of TNT and RDX decrease with the increasing of the temperature,but increase when the pressure is higher than p The highest solubilities of TNT and RDX are 7.42 × 10-3g/gco2 and 8.035 × 10-5 g/gco2,respectively.Based on these results,the process of supercritical separation of wasted composition B is suggested.
