Abstract

original image

Task-specific ionic liquids, containing a carboxylic group attached to an imidazolium cation and associated with a highly stable and hydrophobic anion, generate a fluid that proves to be a successful alternative medium for the oxidative desulfurization of petroleum-based fuels, when used with hydrogen peroxide as an oxidative agent.
