Study of Pseudo-ternary Phase Diagram and Property of Combustion 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,了解乳化柴油的形成原理与柴油乳化的助燃消烟作用;通过实验的开设,使学生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,namely,diesel oil,emulsified diesel oil,diesel oil added combustion catalyst ferrocene and emulsified diesel oil added combustion catalyst ferrocene were prepared by the method of ternary phase diagram;then,their respective combustion efficiency and combustion rate 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.Through the experiment,the students are able to deeply understand the integrated application of physical chemistry in different fields,and thus pay close attention to society and environment.The experiment results show that the design of the experiment is scientifically sound enough to be offered in the physical chemistry experiment course as an comprehensively innovative experiment.
