摘要
利用丙酮萃取分离废旧钝黑铝(A-IX-II)炸药中的钝化RDX,采用静态平衡法对283～323K温度区间内的钝化RDX在环己酮、丙酮以及4种体积比(1∶1、1∶2、1∶3、1∶4)的环己酮-丙酮混合溶剂中的溶解度进行测定;采用Apelblat模型对钝化RDX在环己酮和丙酮中溶解度数据与温度进行了关联,建立了溶解度与温度模型;采用多项式经验模型对钝化RDX在4种配比的环己酮-丙酮混合溶剂中溶解度数据与温度进行了关联,建立了溶解度与温度模型。结果表明,体积比为1∶1的环己酮-丙酮混合溶剂对钝化RDX溶解性最佳;钝化RDX在环己酮和丙酮中溶解度与温度相关系数均在0.97以上;钝化RDX在4种体积比的环己酮-丙酮混合溶剂中溶解度与温度相关系数均在0.99以上。
Desensitized RDX in the waste or obsolete A-IX-II explosive was extracted and separated using acetone,and the solubility of the desensitized RDX in cyclohexanone,acetone and cyclohexanone-acetone mixed solvent with four different volume ratios(1∶1,1∶2,1∶3,1∶4)in the temperature range of 283-323 K was measured by the static equilibrium method.Using Apelblat model,the solubility data of desensitized RDX in cyclohexanone and acetone were correlated with temperature and a solubility-temperature model was established.The solubility data of desensitized RDX in cyclohexanone-acetone mixed solvents with four kinds of different volume ratios were correlated with temperature by polynomial empirical model,and their solubility-temperature models were also established.The results show that the mixed solvent has the best solubility for desensitized RDX when the volume ratio of cyclohexanone and acetone is 1∶1.The correlation coefficients of solubility of desensitized RDX in cyclohexanone and acetone with temperature are higher than 0.97,and the correlation coefficients of solubility of desensitized RDX in cyclohexanone-acetone mixed solvents with four kinds of different volume ratios with temperature are higher than 0.99.
