摘要

离子液体具有蒸气压低、不易挥发、导电能力强、化学性质稳定、可循环利用等特点，具有以下作用：能够替代有机溶剂作为绿色环保的新型溶剂；可以作为催化剂催化化学反应；可以作为电解质溶液参与电化学反应，制作新型电池；可以作为吸附气体的吸附剂等。过去人们认为离子液体不挥发，也不能测量它们的汽化焓，回顾了近年来离子液体的相关研究成果，发现陆续有研究者提出测量离子液体汽化焓的方法，鉴于目前缺少相关总结工作，将系统性地介绍这些方法并阐述其原理，为今后的离子液体研究提供指导。

Abstract

Due to their characteristics

such as low vapor pressure

low volatilization

strong electrical conductivity

stable chemical properties

recyclability and so on

ionic liquids (ILs) can replace organic solvents as a new environmentally friendly solvent

can be used as a catalyst to catalyze chemical reactions

can participate in electrochemical reactions as electrolyte solutions

can make new batteries and so on. It is generally believed that ILs are not volatile and their vaporization enthalpies cannot be measured. However

in recent years

the related research results of ILs have been reviewed

and it has been found that researchers have successively proposed many methods for obtaining vaporization enthalpies of ILs. We will systematically introduce these methods

expounding their principles

and laying a solid foundation for future research.
