Ionic Liquids Dis solve the Problem

If an acid has to be scavenged with a base, the formation of a salt cannot be avoided, but why not form a liquid salt - a so-caUed ionic liquid. The properties of ILs (see 

As they are rather polar materials they often do not mix with solvents or nonpolar product molecules. Using the BASF product 1-methylimidazole as an acid scavenger, an ionic liquid is formed 1-methylimidazolium chloride (HMIMCl), which has a
