超临界状态下TNT-RDX-CO2三元体系固液平衡研究
Solid-Liquid Equilibrium of TNT/RDX/CO2 Ternary System under Supercritical Conditions
摘要
Abstract
The solid-liquid equilibrium data for TNT and RDX in supercritial carbon dioxide (SC-CO2) were measured at 303.0,308.0, 323.0 and 338.0 K,and over the pressures range from 10.0 Mpa to 50.0 Mpa by an ultraviolet-visible (UV-Vis) detector. The effects of pressure,temperature and support effect (SE) between molecules of RDX and TNT on the solubility of TNT/RDX/SC-CO2 system were analyzed. The results show that the solubility of TNT and RDX in ternary system TNT/RDX/SC-CO2 is better than that in binary systems TNT/SC-CO2 and RDX/SC-CO2. The values of SE of TNT and RDX increase first and decrease then with the pressure increasing. The pressure turning point occurred over the pressure range from 25 Mpa to 28 Mpa for TNT and from 13 Mpa to 20 Mpa for RDX.关键词
