Abstract
Ionic liquids and processes and apparatus for their production. The ionic liquids can be low sulfur and low halide carboxylated ionic liquids. The ionic liquids can be produced via formation of at least one intermediate carboxylated ionic liquid, and thereafter subjecting the intermediate carboxylated ionic liquid to at least one anion exchange process.
