【摘要】 用平衡法测定了蒽在N,N-二甲基甲酰胺(DMF)、N,N-二甲基乙酰胺(DMA)和1-N-2-甲基吡咯烷酮(NMP)中20—95℃下的溶解度;应用UNIFAC法建立了蒽在DMF、DMA和NMP中的溶解度的模型方程,并采用MATLAB语言对模型方程进行了求解,计算得到了蒽在DMF、DMA和NMP中的溶解度。结果表明,实验测定值与模型计算值总体规律吻合较好,蒽在DMF、DMA和NMP中溶解度模型计算值和实验值的平均偏差分别为17.56%,15.24%和29.65%,UNIFAC可以预测蒽在DMF、DMA和NMP中的溶解特性,为蒽的溶剂法分离过程中溶剂的选择和工艺优化提供了一定的理论依据。更多还原

【Abstract】 The solubility of anthracene in N,N-dimethyformamide(DMF),N,N-demethylacetamide(DMA) and N-methylpyrrolidinone(NMP) was determined at 20-95 ℃ by liquid-solid phase equilibrium method.The solubility model of anthracene in DMF,DMA and NMP was also established by UNIFAC group contribution method and the model equations were solved through MATLAB.The results show that the experimental solubility data agree well with the prediction values.The average error between calculated results and experimental data is 17.56%,15.24% and 29.65% in DMF,DMA and NMP respectively.The UNIFAC model can be applied to predict the solubility of anthracene in DMF,DMA and NMP.The work provides an elementary basis for selecting a solvent and optimizing process in the separation and purification of anthracene process by solvent methods.更多还原
