摘要
首先,利用Erying绝对速率理论和固-液平衡给出了反推计算丁二酸酐黏度的方法。其次,实验测量了丁二酸酐在1,4-丁内酯中的溶解度数据及该体系的混合溶液黏度数据。再次,使用NRTL模型回归了溶解度数据得到了能量作用参数,以此为基础计算了该混合溶液的过量性质,利用计算结果和Rother关系得到了该混合溶液的流动吉布斯过量自由能。最后,利用这些数据回归得到丁二酸酐黏度模型,该模型可为丁二酸酐结晶装置的设计及优化提供相关参考。
Firstly,the method for back-calculating the viscosity of succinic anhydride by using Erying＇s absolute rate theory and solid-liquid equilibrium was proposed.Secondly,the solubility data of succinic anhydride in 1,4-butyrolactone and the viscosity of the mixed solution were measured.Thirdly,the binary energy interaction parameters of the NRTL model were obtained by correlating the solubility data.Based on this,the excess properties of the mixed solution were calculated.The excess flow Gibbs free energy of the solution was obtained by using the calculated results and Rother＇s relation.Finally,these data were used to derive the succinic anhydride viscosity model,and this model can provide relevant reference for the design and optimization of succinic anhydride crystallization device.
