Patent

CA 2481202

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.

Un aspect de la présente invention concerne des liquides ioniques comprenant un groupe acide de Brönsted latéral, tel qu'un groupe acide sulfonique. Un deuxième aspect de la présente invention concerne l'utilisation d'un liquide ionique comprenant un groupe acide de Brönsted latéral pour catalyser une réaction chimique catalysée par acide de Brönsted. Un troisième aspect de la présente invention concerne des liquides ioniques comprenant un groupe nucléophile latéral, tel qu'une amine. Un quatrième aspect de la présente invention concerne l'utilisation d'un liquide ionique comprenant un groupe nucléophile latéral pour catalyser une réaction chimique assistée par nucléophile. Un cinquième aspect de la présente invention concerne l'utilisation d'un liquide ionique comprenant un groupe nucléophile latéral pour éliminer une impureté gazeuse, telle que le dioxyde de carbone, d'un gaz tel qu'un gaz naturel acide.
