Ionic liquid compositions derived from imidazolium based ionic liquids that have been thermally treated or thermally and oxidatively treated are disclosed. These compositions can be utilized as the medium for oxidation of alkylaromatic compounds and their oxidized derivatives or as a medium for purification of aromatic carboxylic acids. Processes for forming thermally treated A, B-imidazolium ionic liquid solvent composition are also described.
The present invention relates to a carbon dioxide absorbent. In particular, the present invention relates to a carbon dioxide absorbent comprising an ionic liquid, amine and glycol. Since the carbon dioxide absorbent of the present invention can retain excellent CO

absorption capacity despite repetitive regenerations at low temperature, it can reduce energy consumption and a loss of absorbents used, and therefore, can be effectively used for a process of collecting carbon dioxide from exhaust gas and natural gas and separating the same.

A water-absorbent resin dispersion comprising a water-absorbent resin (B) or a hydrous gel thereof dispersed in a liquid or heat-meltable organic active-hydrogen compound (A), wherein said resin (B) is formed by the polymerization of a water-soluble monomer or its precursor and a cross-linker and/or a polysaccharide in the compound (A); and a process for producing a polyurethane resin by the reaction of the dispersion with an organic polyisocyanate compound. As the polyurethane resin is excellent in the capacity and rate of absorption, it is useful as absorbent articles such as paper diaper and sanitary goods, humidity modifiers, cutoff material, and so forth.
