Methods for purifying ionic liquids
Thread Content
Ionic liquids are becoming more and more popular, but some ionic liquids are very expensive. If they can be recycled and reused, these problems should be overcome. However, there are few discussions in the literature on how to purify ionic liquids. For example, if ionic liquids contain water, I want to remove the water as much as possible to achieve the purification effect. I would like to ask if there is relevant information. Let's discuss with each other. This post was last edited by zxh6267 on 2009-3-27 09:46 ]
The boiling point of ionic liquids is much higher than that of water, so vacuum drying can
I understand: Currently, room temperature ionic liquids have received widespread attention as a new type of green solvent. Due to the inherent properties of ionic liquids, we cannot use conventional purification methods to purify ionic liquids. This article briefly introduces room temperature ionic liquids and their development history, types, and synthesis methods. It also introduces in detail the removal methods of common impurities in ionic liquids and the purification methods of AlCl3 type ionic liquids, ionic liquids formed by ion exchange, and ionic liquids composed of ordinary cations and anions.
