Title:
FUNCTIONALIZED IONIC LIQUIDS, AND METHODS OF USE THEREOF
Document Type and Number:
WIPO Patent Application WO2003086605
Kind Code:
A3
Abstract:
One aspect of the present invention relates to ionic liquids comprising a pendant Bronsted-acid group, e.g., a sulfonic acid group. Another aspect of the present invention relates to the use of an ionic liquid comprising a pendant Bronsted-acidic group to catalyze a Bronsted-acid catalyzed chemical reaction. A third aspect of the present invention relates to ionic liquids comprising a pendant nucleophilic group, e.g., an amine. Still another aspect of the present invention relates to the use of an ionic liquid comprising a pendant nucleophilic group to catalyze a nucleophile-assisted chemical reaction. A fifth aspect of the present invention relates to the use of an ionic liquid comprising a pendant nucleophilic group to remove a gaseous impurity, e.g., carbon dioxide, from a gas, e.g., sour natural gas.
