| 摘 要： | 介绍了一个综合性物理化学实验:赖氨酸钠溶液吸收CO2的气液相平衡与化学动力学。针对物理化学中相平衡和化学动力学2章内容,开展实验教学。本实验以易得的赖氨酸、氢氧化钠和CO2为原材料,通过试剂配制、气液吸收和数据采集等实验操作,分析得到赖氨酸钠-CO2体系的相平衡数据(温度、压力、溶解度)和吸收过程的化学动力学特性(表观速率常数)。结合基本参数测量(质量、温度、压力与时间等)和热力学与动力学函数计算,既提高学生的综合实验能力,又加强其对多章节知识点的融会贯通,激发其科研兴趣和探索精神。 |
| 关 键 词： | 二氧化碳 赖氨酸钠 气液相平衡 吸收动力学 溶解度 表观速率常数 |

| Abstract: | A comprehensive experiment of physical chemistry was introduced to measure and calculate the vapor-liquid equilibrium and chemical kinetics of the sodium lysine-CO2 system,which is related to two chapters,phase equilibrium and chemical kinetics,in the course of physical chemistry.L-Lysine,sodium hydroxide,and CO2 were used in this experiment,including the operations of reagent preparing,gas absorption,and data acquisition.Phase equilibrium parameters(temperature,pressure,and solubility)and chemical kinetics properties(apparent rate constant)were calculated and analyzed,to improve the operation ability of students,enhance their understanding of the course knowledge,and inspire their exploration on scientific research. |
| Keywords: | carbon dioxide sodium Lysine vapor-liquid equilibrium absorption kinetics solubility apparent rate constant |
