聚焦光束反射测定HMX溶解度及关联

用聚焦光束反射(FBRM)和全自动反射仪(Labmax)组成的动态在线分析系统测定了奥克托今(HMX)在N,N-二甲基甲酰胺(DMF)、1,4-丁内酯和环己酮中的溶解度。用Apelblat模型和多项式对实验数据进行了关联。结果表明:对多项式模型,HMX在DMF、1,4-丁内酯、环己酮中溶解度的平均相对偏差分别为0.019919,0.013156,0.033673;相关系数分别为0.99948,0.99758,0.99768。对Apelblat模型,HMX在DMF、1,4-丁内酯、环己酮中溶解度的平均相对偏差分别为0.004435,0.005204,0.009582;相关系数分别为0.99857,0.99689,0.99565。说明,HMX的溶解度曲线在Apelblat模型中符合较好。

Determination and Correlation of HMX Solubility by FBRM

The dynamic online analysis system consisted of focused beam reflectance measurement (FBRM) and automated lab reactor (Labmax) was used to determine the solubility of HMX in N,N-dimethylformamide (DMF),1,4-butyrolactone and cyclohexanone. The experimental solubility data were correlated with Apelblat model and polynomial empirical equation, respectively. The results show that the average relative deviations and the correlation coefficients of HMX solubility in DMF, 1,4-butyrolactone and cyclohexanone are 0.004435, 0.005204, 0.009582 and 0.99857, 0.99689, 0.99565 for Apelblat model, and 0.019919, 0.013156, 0.033673 and 0.99948, 0.99758, 0.99768 for polynomial empirical equation,showing that the solubilities of HMX are well-fitted in the Apelblat model.
