CA 2463290
Zwitterionic imide compounds are provided according to the formula: R1-SO2-N-- SO2-R2+, where R1 and R2+ are any suitable groups. Typically R1 is a highly fluorinated alkane and R2+ contains a quaternary ammonium group or a heteroatomic aromatic group having an cationic nitrogen, such as: pyridiniumyl, pyridaziniumyl, pyrimidiniumyl, pyraziniumyl, imidazoliumyl, pyrazoliumyl, thiazoliumyl, oxazoliumyl, or triazoliumyl. Zwitterionic liquids are provided, typically having melting points of less than 100 ~C and typically having a solubility in water of less than 5% by weight.
L'invention concerne des composés d'imides zwitterioniques de formule R¿1?-SO¿2?-N?-¿-SO¿2?-R¿2??+¿, dans laquelle R¿1? et R¿2??+¿ représentent des groupes appropriés quelconques. Généralement, R¿1 ?représente un alcane extrêmement fluoré et R¿2??+¿ contient un groupe d'ammonium quaternaire ou un groupe aromatique hétéroatomique comprenant un azote cationique, tel que pyridiniumyl, pyridaziniumyl, pyrimidiniumyl, pyraziniumyl, imidazoliumyl, pyrazoliumyl, thiazoliumyl, oxazoliumyl ou triazoliumyl. Cette invention a également trait à des liquides zwitterioniques qui présentent généralement des points de fusion inférieurs à 100 ·C et une solubilité dans l'eau inférieure à 5% en poids.
