ILSEPT - 5th International Conference on Ionic Liquids in Separation and Purification Technology


As the future situation regarding international travel remains uncertain, the organizers have decided to postpone the 5th International Conference on Ionic Liquids in Separation and Purification Technology until 2023.

The aim of the Fifth International Conference on Ionic Liquids in Separation and Purification Technology is to provide a forum for researchers in academia, national laboratories, and industry to share and discuss their latest results on the use of ionic liquids in separation applications. This meeting will build on the momentum from the previous ILSEPT meetings held in 2011, 2014, 2017, and 2019.

Ionic liquids are an exciting class of materials that possess unique properties such as negligible vapor pressure, tunable solvating power, wide liquidus range, and high thermal stability. Due to these unique properties, they have found a wide range of applications in fields as diverse as petrochemicals, fine chemicals, pharmaceuticals, biotechnology, hydrometallurgy, environmental remediation, and nuclear sciences. Ionic liquids provide novel intensified separation and purification technologies that enable major contributions towards establishing the sustainable processes required for the future process industry. Commercial examples include solvating power for extractive separations, ability to separate azeotropic mixtures, and their ability to dissolve a wide range of natural materials such as cellulose, carbohydrates, and lignin.

The scientific program will offer plenary lectures, submitted oral presentations, and poster sessions. Outside the session lecture theatres, you will also find numerous exhibitors presenting the latest equipment and applications using ionic liquids.
