摘　　要：本实验是化学工程与工艺专业实验的重要组成。通过控制温度,调节CO2压力使其达到临界状态,进而了解临界乳光、整体相变和汽液二相模糊不清的三种现象。在不同实验温度(低于、等于和高于临界温度)下,测定CO2的PVT曲线,利用热力学原理理解CO2临界现象。通过实验提高学生对CO2临界状态的感性认识和实验动手能力,培养学生理论联系实际的思维习惯。This experiment is an important part of chemical engineering and technology experiment.By controlling the temperature and adjusting the pressure of CO_(2) to reach the critical state,the three phenomena of critical opalescence,global phase transition and vaporliquid twophase ambiguity can be understood.The PVT curves of CO_(2) were measured at different experimental temperatures(below,equal to and above the critical temperature),and the critical phenomenon of CO_(2) was understood by thermodynamics.Through the experiment,the students'perceptual knowledge of CO_(2) critical state and experimental ability are improved,and their thinking habit of integrating theory with practice is cultivated.
