  • Patent number: 7737102
    Abstract: A novel class of ionic liquids and methods for their preparation are disclosed. Specifically, these novel ionic liquids can be derived from anionic surfactants, such as alkyl aryl sulfonates, and mid-chain branched derivatives of alkyl sulfates, alkyl alkoxy sulfates, and alkyl aryl sulfonates. In addition, novel ionic liquids can be derived from other anionic surfactants, such as methyl ester sulfonates (MES), alkyl glycerol ether sulfonates, and alpha olefin sulfonates. Anions may be paired with a variety of cations to achieve various advantageous properties. The present invention also relates to compositions containing these novel ionic liquids and method of using the same.

  • Patent number: 6379634
    Abstract: A method of dissolving in an ionic liquid a metal in an initial oxidation state below its maximum oxidation state, characterized in that the ionic liquid reacts with the metal and oxidizes it to a higher oxidation state. The initial metal may be in the form of a compound thereof and may be irradiated nuclear fuel comprising UO2 and/or PuO2 as well as fission products. The ionic liquid typically is nitrate-based, for example a pyridinium or substituted imidazolium nitrate, and contains a Bronstead or Franklin acid to increase the oxidizing power of the nitrate. Suitable acids are HNO3, H2SO4 and [NO+]. Imidazolium nitrates and certain pyridinium nitrates form one aspect of the invention.
