摘要
为了让学生更好地理解非理想体系汽液相平衡的特点,基于学科前沿和研究基础,设计了乙醇-离子液体等压汽液相平衡测定的综合创新实验。该实验主要包括等压汽液相平衡的实验操作、非理想物系相平衡数据分析、阿贝折光仪分析样品含量、模型关联以及分子水平机理分析等,是一个涵盖了化工热力学、物理化学、物理光学、数值分析和量子化学等学科的综合实验。与传统二元体系汽液相平衡实验相比,该实验更具有探索性和创新性,操作简便省时,重复性高,提高了学生创新思维能力和科学研究意识,训练了学生发现问题和分析解决问题的综合能力。
A comprehensive innovative isobaric vapor-liquid equilibrium(VLE)experiment for the ethanol-ionic liquid system is designed based on the advanced discipline and research foundation,in order to get a better understanding of the VLE behavior of the non-ideal systems.The project mainly includes the isobaric experimental operation,the analysis of non-ideal VLE results,and the analysis of the sample content by the Abbe refractometer,the model correlation,and the molecular level analysis,etc.The comprehensive experiment covers the disciplines of the chemical thermodynamics,physical chemistry,physical optics,numerical analysis,and quantum chemistry.Compared with the VLE experiment of the traditional binary system,this experiment project is exploratory,innovative,convenient,time-saving and persuasive.It improves students'skills of the innovative thinking and scientific research,and trains the comprehensive ability to find,analyze and solve problems.
