摘　　要：介绍了超临界GAs超细化和包覆改性过程中,有机溶剂在超临界CO_2中的溶解度测试原理、方法和装置,并对丙酮和乙酸乙酯在超临界CO_2中的溶解度进行了测试。结果表明:溶解度主要受系统温度、系统压力的影响,且系统压力对溶解度的影响大于系统温度对溶解度的影响。本研究为超细炸药的制备和包覆改性超临界GAS技术研究提供了基础数据。Test theory, method and equipment used to test solubility of organic solvent in supexcritical carbon dioxide were introduced, in the course of ultra-fining and coating modification by supcreritical gas anti-solvent. The solubility of acetone and ethyl acetate in supercritical CO2 were tested. Test results showed the solubility in supercritical CO2 was mainly affected by system pressure and system temperature, and system pressure was more important factor. The study provided basic data for the preparation of ultra-free explosives and its coating by supercritical CO2 technology.
