Alkylsulfuric acid ionic liquids: a promising class of strongly acidic room-temperature ionic liquids. Issue 25 (7th March 2016) - Dupont, David
Abstract : Alkylsulfuric acid ILs are simple to make and offer a more strongly acidic alternative to sulfonic acid ILs for applications in catalysis, metal extraction and dissolution of metal oxides. Abstract : Strongly acidic (p K a ≈ −3.5) room-temperature ionic liquids (ILs) with –OSO3 H functionalized cations are introduced. The strong acidity, easy synthesis, and better physical properties of these R–OSO3 H ILs make them excellent alternatives to the well-known sulfonic acid (R–SO3 H) ILs, especially in the domain of metal processing.
