“水-柴油微乳体系拟三元相图绘制与燃烧性能测定”实验教学设计

Experimental teaching design of drawing pseudo-ternary phase diagram and determining combustion property of diesel oil microemulsion

实验中将三元相图的绘制方法与量热技术相结合,选择备受关注的能源与环境问题,结合水-柴油体系的微乳化原理与拟三元相图的绘制,配制不同性质的乳化柴油,并通过氧弹量热装置测定柴油、乳化柴油以及添加助燃催化剂二茂铁后燃油的燃烧效率与速率,以了解乳化柴油性质、形成原理与柴油乳化的助燃消烟作用,使学生通过实验,加深了解物理化学原理在不同领域的综合应用,关注社会、关注环境。教学实践结果表明,本实验设计科学合理,可作为物理化学实验课程中综合创新实验开设。

In this experiment,four series of diesel oil——diesel oil,emulsified diesel oil,diesel oil added combustion catalyst ferrocene and emulsified diesel oil added combustion catalyst ferrocene were prepared under a method of drawing pseudo-ternary phase diagram,then the combustion efficiency and combustion rate of them were determined by oxygen bomb calorimeter,and the forming principle of diesel oil and the role of combustion smoke of emulsified diesel oil were studied.It is shown that through the experiment the students can deeply understand the integrated application of physical chemistry in different fields,and pay close attention to the society and environment.
