测定5-氯-2戊酮和环丙基甲基酮的物化性质:密度、黏度、摩尔体积、热膨胀系数和表面张力。测定5-氯-2-戊酮(1)+环丙基甲基酮(2)二元体系的汽液相平衡(VLE)，并应用Aspen Plus V11中Van Laar方程、Wilson方程和NRTL方程对实验数据进行关联，回归得到二元交互参数。实验结果通过热力学一致性检查。该研究不仅补充了汽液相平衡数据库，也为5-氯-2-戊酮与环丙基甲基酮的分离提供热力学数据。
Materialization properties and vapor-liquid phase equilibrium for 5-chloro-2-pentanone with cyclopropyl methyl ketone
The physical and chemical properties for 5-chloro-2-pentanone and cyclopropyl methyl ketone,including density,viscosity,molar volume,thermal expansion coefficient,and surface tension,were determined.The vapor-liquid phase equilibrium(VLE)of the binary system of 5-chloro-2-pentanone(1)+cyclopropyl methyl ketone(2)was further determined,and Van Laar equation,Wilson equation,and NRTL equation in Aspen Plus V11 were applied to correlate the experimental data.Moreover,the binary interaction parameters were also obtained by regression.The experimental results were confirmed by a thermodynamic consistency examination.This study not only complements the vapor-liquid phase balance database,but also provides thermodynamic data for the isolation of 5-chloro-2-pentanone and cyclopropyl methyl ketone.
