| Abstract: | Combined with the teaching requirements and frontier direction of physical chemistry and instrumental analysis in geology, a comprehensive experiment on the extraction and separation mechanism of methanol acetonitrile azeotrope by ionic liquid is designed. The effect of ionic liquid on isobaric phase equilibrium of methanol acetonitrile system is studied, and the mechanism of extraction separation of azeotropic system by ionic liquid is analyzed by using 1-butyl-3-methylimidazolium trifluoromethanesulfonate(BMIM] OTF) as extractant and methanol acetonitrile azeotrope system as the research object. This experiment combines physical chemistry, instrumental analysis, college chemistry and other professional courses, organically integrates the basic knowledge of the discipline with the innovative research of large-scale instruments, tamps students’ theoretical knowledge, stimulates their interest in scientific research, and improves their innovative ability. |
